Yes, the library we disable by default but that some downstream projects
enable to easily support both projects without a massive amount of custom
codepaths or ifdeffery.

You seem to have forgotten the very long years where Debian shipped libav
and not ffmpeg. Had we not merged that library and dropped API/ABI support
from the get go, who knows what would have happened.

I'd very much like if every other of your emails could stop being so
aggressive when it's completely unjustifiable. You seem to be reacting to
some old frustration with this code (or code you dislike in general) rather
than to an email by "people like me" where I'm simply expressing the need
to not disrupt downstream projects too much unless necessary.

My concerns are very valid, and i ask you again to drop the aggressiveness.
You'll write a shim? That's great. Just don't be a dick when you're informing
me about it.

And for that matter, if the general consensus is to drop all pretenses of API
compatibility then i have no issues with all this. You wouldn't even need to
write a shim in that case.
