Good question. Perhaps one might argue that unicode-math should not rely
on anything to be taken from CM. If something is not readily available
in XeTeX such as \overbrace, it should probably provide its own
redefinition in terms of Unicode slots (if that is possible). However,
this might also get trick in terms of which building blocks are encoded
as Unicode slots or only in the Private Use Area.
Hmmm, this probably still needs more thinking...
