Because it's quite some work and we'd need to start *NOW* - but it requires some people to actually work on it and take control.

There wasn't some kind of (accidental?) ABI breakage? I would not want 12.2 to be incompatible with everything else.
Haem, not sure when that started to matter - but you're incompatible as soon as you compile against latest glibc symbols.
GCC 4.7 libraries installed on a 11.1 (yes, I know ...) work just fine. They are ABI (backward) compatible. Everything else would be a bug.
Using Google to remember... What I was thinking was about is http://lists.fedoraproject.org/pipermail/devel/2012-February/163320.html. But it seems the problem was fixed before the 4.7 official release and they had the problem just because they were using pre-release versions.
Yes. Note that 4.7 is not yet officially released.
