As I said, if the use of annotate is the only problem, it can be disabled with a
simple gdb command just after gdb-mi.el starts gdb:

        set annotate 0

This trivial change should address all the bugs you referred to.

The use of "interpreter-exec" is just to make sure commands go through MI even
if the user omits the "-i=mi" argument.

Then the check you say is just to cover the case of the user starting gdb with
"-i=tui", which will probably never happen.
