As pointed out before, it doesn't break anything but adds a workaround
for scenarios which are _now_ broken (16/32 bit target code exported as
64 bit is widely useless for gdb today). Sorry, but you never explained
to me how user are _currently_ supposed to debug under that conditions,
namely 16/32 bit code executed by qemu-system-x86_64.

I could offer to add a monitor command so that one can additionally
set/override the register representation during runtime that way. I do
not see a use case for it based on all the scenarios I'm aware of or
personally ran through the last year, but if it helps acceptance.
However, only a command line switch locking down the mode would solve
just half of the real-world problems.
