Of course, but the combination math-packages + MusiXTeX is virtually
non-existent, whilst XeTeX/fontspec + MusiXTeX is highly desirable and
sophisticated (they are together actually the best note typsetting
system in existence, imagine what you can do with Medieval music
manuscripts, etc.), so one could expect that many users would like to
use it.

And I somehow felt that a music package has the right to keep \breve :)
(Of course, this is not complaint, just friendly chat.)
