Depends on the user, I suppose.  Having 32-bit and 64-bit variants of
the same architecture in a single binary would be useful.  Having
big-endian and little-endian variants of an architecture supported in
a single binary would be useful (bonus points if you don't duplicate
target-specific code excessively).  Having a gigantic all-singing,
all-dancing QEMU is perhaps not so useful, but between there and where
we are now, there are definitely useful points.
