I think it's pretty clear that no one else likes the idea of
negotiating.  I certainly don't.

I believe that printing the latest stable version of MI is plenty
adequate.  If the front end wants a development version of MI it can
use -i=mi; if it wants the latest stable version it can use that
version; if it does not recognize that version it can use the latest
version it recognizes.  If you encounter a situation in which that
version no longer works, have it removed from GDB.
