With the same kind of reasoning, you could argue that it should be
able to brew coffee.

Nope.  If at all, this would be done using a flag similar to the Omega
flag.  No sense at all making the Command menu even longer.  That's
not the way we solved this sort of problem in the past, and it messes
up the command shorthands without good reason.  And we don't check for
binaries at runtime if we can avoid it.

As long as there is no developer actively using XeTeX (or having it
installed), I doubt we can reliably figure out which commands to call
and what options are not available.  Then it seems like it has its own
dvi-like files (what a mess).  And it is not clear to me whether it
can produce PDF.  This can't be done sensibly in a hurry, and it can't
be done without a developer actively playing around with XeTeX.
