Changing the system default GCC version, like it seems you did, is not good practice in environments with conservative package policies.

There's also no need to do that, since nobody prevents users from installing newer versions alongside old ones, and invoking them directly.

Even not considering the fact that different GCC versions can coexist, complaining about this breakage in absolute terms doesn't make any sense. Releases changing default compiler versions inevitably cause more breakages with packages who haven't been updated to be compatible with newer GCC versions. So ultimately it's a matter of choosing the distributions with the appropriate release model, not a matter of Ubuntu/Debian breaking stuff.

Libav has also been deprecated in Ubuntu long ago, so it's not clear what you refer to. If you happen to refer to the transition from and back to ffmpeg, that's very old history.

I'm referring to the libav* libraries which are part of the ffmpeg project (not the horribly-named libav fork) - and external debian repos providing updated version of those (due to better codec support in media players, etc) such as debian-multimedia
