If lilypond defaults to 384, and user sets it to something that a device cannot
handle, that is a user problem I guess.

I don't know about thoose, one just have to choose a name and
possible mention other names used. Usually I tend to use names from
standard papers because then I can point to paper X page n. I don't
know what the regular developers think about this, but if you
know your stuff, I wouldn't mind if you choose the name.
What we are missing now is some info of how to do handle
\midi {
\divisions = 960 % or
\ppq = 960
}
in the source.
