Actually, you did ignore. The below text refers to something older.

Yes, you told me this, before USE=vanilla even existed for gcc. When
there's no implicit claim that installed GCC is official GCC, it's much
less of a problem that it's not. Back then, I never complained that the
installed GCC wasn't the official GCC, only that (a manually installed)
official GCC wasn't a supported compiler. And I did not ask for an
official way to disable the stub patches then, I only asked how I could
do it for my own system.

Thanks. I hope that if a similar situation comes up, ebuilds will use
test-flags instead of assuming the option is valid, though.

I didn't point that out to you, I pointed that out to another of the
toolchain guys. I'm not completely sure who, but I think it was
Halcy0n.

Thanks again.
