As long as everybody agrees, I'm fine with this. I don't want angry
users complaining that their app is crashing.

Yes, something should be updated. I just wasn't sure minor was enough.

I'll push them at the same time.

Since you're quite actively working on it, to say the least, having a
dedicated branch/repo for lavfi would allow you to work as quickly as
you want, and the master would catch up from time to time. This model
also has the advantage that when reviewing, one can look ahead in the
development branch and see where things are headed, thus helping to
understand the reason for making changes. Without this path ahead
clear, some of your patches have seemed a bit mysterious in the past.
