The BRZ and Impreza are far closer to each other than the Z and FX. The G coupe/sedan is to emphasize the sharing in a more obvious way than the Z/FX.
You cannot 'prove' a chassis is different because, for example, an FA20 cannot swap into an AWD Impreza. Why? Because the differences are part of the modular aspect, and there are less critical/expensive parts to allow for easy changes. As an example, you cannot take a 1JZGTE from a TT Mk3 Supra and directly swap it into a 7MGTE Mk3 Supra. They are different engines and require different engine mounts, bell housing, piping layout, etc... But they are the exact same chassis, let alone shared platforms. The same types of changes allow for differences within a platform with minimal engineering changes because the flexibility is designed in.
Does this show what I'm talking about a bit better? Chassis sharing isn't disproved by 'this one or two parts do not fit' arguments. The G example was perhaps an oversimplification failure on my part.

You seem to have a way of overgeneralizing.
You can't make a statement like this:

And then ignore the fact that the major components of a G35 sedan and coupe are literally direct swaps or identical.
On your mk3 Supra example, the engine might not be a direct swap, but I would imagine that the suspension, brakes, interiors, and virtually everything else would be. By definition, that makes those Supras (and the G35 sedan and coupe) much closer than, say, a BRZ and Impreza where no major parts swap over or were even engineered to work in the other car.
Your other statement:

Is also overgeneralizing, to put it kindly.
If it makes you feel any better, I'd hardly call the FX35 a "mildly modified" 350z FM platform either.
