Without myself trying to take sides on this, one could argue:
ffmpeg chooses not to create "illegal" files. It is friendly enough
to demux/decode those created by others though, allowing you to carry
the data over.
Why do you need to create the same/similar format that Sony and Canon
do? Do you want the resulting MP4 to be read by a particular software?
Why does the audio need to be copied losslessly? Why are the MOV or
Matroska containers not alternatives?
 Agreed it can in some other cases.
