FFmpeg supports opening almost every format, form the most obscure
and dead formats from 20 and more years ago. To the most recent cutting
edge. I think any fear that we would drop support for FFv1 is quite
unfounded. But if we really lost all sanity, and our servers would be
all bombed by NATO. Still everyone who ever checked out a git version
does have not just one checkout, he has _every_ revission that has
been ever pushed into public by us. Thus he can always checkout and
compile that version with which his video was encoded and decode
it to YUV or RGB RAW. This is very hypothetical, we wont drop support.
That said, FFmpeg is open source and free software, theres no risk
of being locked into a format that cant be converted all of a sudden
everyone has the code to decode it ...

There will always be a question for which you do not know the correct awnser.
