Exactly! EF mount is Canon's crown jewels and they cannot afford to abandon or replace it. It is also not suitable for a mirrorless system.
Huh? Some owners of Sony FF mirrorless cameras use Canon EF lenses.
Well you can shave with a razor tied to a broom handle, but that doesn't mean it's a solution or desirable.
You don't know if you don't experience. If you try you will change your perception.
The point is not that you can't get good results adapting EF lenses to Sony but that EF mount is not suitable as a mirrorless mount for Canon.
Oh, that we don't know until Canon release a FF mirrorless. I agree EF lenses are not suitable on EF-mount mirrorless, but should work as good as e-mount on EF-M mount if Canon designed well.
There are a number of reasons for this which I'll go into if you want.
To me and many adapted lenses are both solution and very desirable, such as still the best 24-70L/2.8 II zoom from Canon in this category over all competitors including Sony own FE 24-70 GM, Canon is sharper at 70mm side and has (much) better sunstars.
The Lens Rentals bench testing of the 24-70 Sony shows it to be be slightly better than the Canon. I don't know about the sunstars.
Yes, I have read many happy owners. But in consensus, Canon version is better at 70mm side. Guess similar to FE 16-35G/4.0 OSS that I used to own. At 16mm side, it's as sharp as and actually slightly sharper in center area than Canon EF 16-35L/4.0 IS that I currently adapted on Sony bodies, but Canon is sharper at 35mm side.

I don't think Sony should even bother in designing and manufacturing TS-E lenses as Canon already done the best, and they are MF lenses anyway, just so much easier and effective on e-mount with EVF and focus assistant tools.
There is no burning need for Sony to design a TS lens, as you say and I don't think they will bother unless they can make an AF one. The A-mount STF lens was manual focus only and the new e-mount 100 STF is AF.
Don't think TS-E lenses can be AF But relative new FE 100mm STF is an awesome portrait lens, although I still will get one between 85 GM and forthcoming Sigma e-mount 85 Art (just patiently wait to see e-mount Art lenses), just more useful to me than specialized STF lens.
I have seen sunstars from FE 24-70 GM, not very impressive compared to Canon's version. Actually this is a general issue that Sony lenses so far are still not very good in sunstars which happen important to me as I shoot many evening cityscape photos, but some FE lenses are great in sunstars such as Zeiss Loxia 21 and CV 15mm primes. One of reasons I will keep EF 24-70L/2.8 II and likely will be the only EF lens keep after one or two years. Will replace EF 16-35L/4.0 IS with FE 16-35 GM and eventually will sell 500L/4.0 IS.
Most EF-mount lenses at 200mm or below FL AF very fast on e-mount. Sure get a hit in very low light where MF is handy to use.
Personally I had a big surprise a few weeks ago on my legacy Canon 500L/4.0 IS. Initially I wanted to buy a 5D IV just to leverage this particular lens (and 1.4x TC III still possess) and planned to sell it after I got A9 instead of 5D IV. Until then I virtually never used the Advanced mode but just default Green mode with MB4-T adapter, and 500L IS only can AF in 1/3 narrow area in EVF on A9 and still only 1/3 in both horizontal and vertical center area AF points are reliable. Thought I should sell it then. Then I decided to why not give a try in the Advanced mode after the latest FW update. Wow, jaw dropped that its AF (under either AF-S or AF-C) beautifully in entire EVF that can use all AF points (covers 93% of entire frame). Very fast and accurate AF. I tested in evening near total dark kitchen with only one table lamp highlight behind me toward kitchen (completely light off there) that is a bit more than 10m away. Just cannot believe that it still can AF at so low light - wide open at F/4, 1/60 sec (on 500mm FL) and max native ISO in A9 (51200 ISO) and even still can AF on subject with pretty low contrast such as on microwave oven surface. Then I tried my trusty 1D III that max ISO out at 6400, it's so dark (virtually cannot see anything in OVF) and failed to lock on any subject in the kitchen. I cannot be happier as I don't need to sell it now and has no issue in another Africa safari to use on A9 where much brighter than my tested dark kitchen. The only issue is that lens weight 8.5 lb. Might still get Sigma 500G/4.0 OS Sport later when native e-mount released, that is more than 1 lb lighter. Tried EF-mount version Sigma 500mm in the last PhotoPlus Expo thru MC-11 adapter and it AF very well on A9.
