He did? I thought he said "who knows", meaning he didn't know. How could
he create policy on this if he doesn't know.

Yes, I understand.

If GDB is going to support 1 stable version of the MI protocol at a time
then just have it print the version on startup. There is no negotiation
that needs to take place.

If GDB is going to support multiple stable versions of the MI protocol
at a time, then have it print all of the versions like you suggested.
Also, above what you suggested, I think the front end should be able to
select the version it wants from the list. Is this OK?

I'd like to work on this patch as soon as possible, so that I can start
using it. Is the multiple stable version approach with negotiation OK?
