Though the counter pull is popularity of Monkey's Audio.

Right. See below.

There could only be support for the current implementation in FFmpeg  
and inform users that they have to recompress their files with the  
current implementation to be able to use them, maybe if we're nice,  
displaying which version the file was encoded with and which version  
FFmpeg supports.
