Great body/lens pairs

I can't agree with your claims about dxomark,

Of course you can agree, if you know what you are talking about.

But, allow me to show you.

Lets take a lens we KNOW how it performs, so we can catch DXOmark's lies.

Lets look at the Canon EF 16-35mm f2.8 L USM II. It is known for not being sharp in the corners wide open. And that things gradually improve when you stop down. Everyone knows that. Well, everyone with some knowledge.

Now lets have a look at what DXOmark says. Sharpness 16mm wide open, on a 5D mark III:

Wow, really? Seriously? That does not look right. Where are those soft corners?

Lets stop down to f5.6, the next available result.

Oh look! There are those soft corners. Clearly something has gone very wrong in 2012, when they first "tested" this lens.

Lets look at their tests on newer camera bodies. A 5DS-R for instance. Wide open at 16mm:

Uhmmm...

Woah, the same nonsense results, years later.

Ok, then lets just look at APS-C.

Wide open at 16mm:

Ok... and at f5.6?

Right. There you go. Not only is their "mpix" "measurement" a nonsense number/calculation, but they do NOT do measurements of lenses on different bodies. They just do a measurement once on one camera, and "calculate" "results" for other bodies from that.

And the results from the actual tests are HIGHLY unreliable, to say the least.

but we can leave it at that, because the point of my original post is that there are lenses that exceed the limitations imposed by the APS-C sensor,

That point is wrong. The APS-C sensor has very high resolving power, compared to most FF sensors. The 18mp sensor in your T4i is comparable to a 46mp FF sensor. It is the sensor that exceeds the abilities of a lens, not the other way around.

and to a lesser extent, the version in the T4i. It's like putting 175SR15 tires on a Ferrari. I think there are some good lenses that will match well with the capabilities of the Canon APS-C cameras as well as meet that 80/20 performance/cost trade-off. I'm looking forward to hearing people chime in with their personal experiences.
