No, I'm asking specifically about the master branch of the GDB
repository.  (I understand the reasoning behind disallowing that for
the release branch, given the practice that bugfixes get applied to
master first.)

Where was that discussed, and what were the reasons?

Rebasing loses information (e.g., if I merged from master several
times during my work).  And I don't really see the downsides of
merging to master.  I also don't object if others want to rebase, I
just don't understand why force everybody to do that.

??? Why would I need to do that for submittal?  Git is perfectly
capable of diffing against any revision of any branch, right?

I have nothing against that, I just didn't know about a similar
restriction for master, and was unpleasantly surprised.
