Lack of up to date pancakes in M43?

I own a Fuji X system, but I notice that I prefer to take my Fuji x100 or Nikon 1 system for street / general photography.

So the thought came that an Olympus E M10 with a pancake and sometimes a portrait lens might be a flexible alternative for the x100 that is smaller than the Fuji X system.

When researching I found that the Pana 20mm 1.7 has outdated focusing speed, while the Pana 14mm and Oly 17 mm had less than stellar IQ. The Pana Leica 25 mm, Pana 25mm, and newer Oly 17mm are nice lenses but no pancakes.

I was somewhat surprised that there seem to be few modern pancakes for M43 while small size is apparently an argument used in favour of M43. For all practical purposes is my XE2 wit 35mm 1.4 as big as am Olympus om with the Pana Leica 25mm.

I want to try M43 but the system gives me no obvious roadmap or compelling argument for my simple and no tele desires.

I hope I am wrong and missing a few things; please point out what (products) I missed because I real feel drawn to M43.

Buy a Panasonic GX80/85 instead of the EM10 if you want to use the 20mm 1.7. It's not slow at all on any recent Panasonic body. Most of the time it's just as quick as any other lens. In other words, instant. There are two occasions where it's not quite as quick as other M43 lenses.

First is if you often focus from closest focus to infinity. The lens physically moves which is why it takes longer. We're only talking fractions of a second longer though. In real world I don't find I often need to do this anyway, YMMV.

The second instance where it slower is when the lens hunts because there isn't enough contrast in the scene. It's hunting takes longer than other lenses. I often just release the shutter button and focus on something with more contrast as soon as the lens starts to hunt.

I use the 20mm a lot for street shooting, it's a great lens and pretty inexpensive.
