To avoid .gdbinit, start gdb with -nx.  If you want, then source
.gdbinit or $HOME/.gdbinit yourself.  You'll have to duplicate the
search for gdbinit files, but it's not as if that's a big deal.

As for whether you can parse the response of -interpreter-list, I don't
think there's any point in planning for that sort of drastic change to
the protocol.  We're talking about selecting a version of MI; all
versions of MI are supposed to follow more or less the same formats.
