IMVHO, we should try to exclude active GDB maintainers from the
committee. Given the fallout from the incident(s) that led to these
discussions, I think the committee's membership should be as remote
as possible from any doubts regarding their objectivity; including
people some of whom were involved in the kind of personal conflicts
that led to this would go against that, IMHO.
I see where you are coming from, but I think that the steering
committee does need to have some people paying close attention to the
direction that the gdb source code is taking. I think it would be
hard to do that with no regular gdb maintainers at all.
