For packagers? They have all required version information in their own
packaging setups already. All they need to implement is a way to automatically
convert that into a configure switch. Once this is implemented, it'll work
without further effort.
For GCC? It's not much different than the other predefined macros. Do they
pose a maintenance burden?

Then the compiler is identified as vanilla GCC and if it differs from it
there's not much I can do about it. I'd report a bug, possibly provide a
patch, and continue crying like I do these days. ;)

If just the #ifdef __GNUC_<vendor>__ is available, that would already go a
long way. Again, I'd report a bug, possibly provide a patch, and hope for
better days.

I agree. This will not be the silver bullet. But I believe it would still
improve things.
