It's hard enough to keep localized strings updated for every release
within a single code tree. Beyond that, you expect that every *client*
will update its localized strings for every *server* release? If you
agree that is an unrealistic expectation, then even a "highly
structured" reporting mechanism won't help.

On the other hand, if you truly want to invest the energy required to
localize qemu (the server), I can imagine setting the per-client locale
as a monitor command.
