It's a good idea, but we need to be strict about it. As in, we need to 
state that the moment the branch is made it's a definite feature freeze, 
and only fixes, documentation changes and similar may be cherry-picked 
into it (meaning nothing that usually comes with a version bump, even if 
micro), much like we do for a point release, even if the initial release 
was not tagged yet.

Reverting something in the release branch is already going to be dirty 
no matter what, because we do a minor bump to ensure the release has its 
own soname. Right now that'd mean 5.0 will be lavf 59.13, while lacking 
a demuxer available in lavf 59.12
