I don't think the LF has done much actively on the lists ... we've been
trying to self police.

Well, we can agree to differ since this isn't relevant to the main
argument.

That's a bit of a straw man: I never said or implied "bad person".  I
gave two examples, one from direct list interaction and one quoted from
Kent of what I consider to be red flags behaviours on behalf of a
maintainer.

I don't believe any of us have been unable to work with a fairly
prolific contributor for 15 years ...

Actually, I don't think this is a problem: a new feature has no users
and having no users, it doesn't matter if it loses its only maintainer
because it can be excised without anyone really noticing.  The bus
problem (or more accurately xkcd 2347 problem) commonly applies to a
project with a lot of users but an anaemic developer community, which
is a thing that can be grown to but doesn't happen ab initio.  The
ordinary course for a kernel feature is single developer; hobby project
(small community of users as developers); and eventually a non
technical user community.  Usually the hobby project phase grows enough
interested developers to ensure a fairly healthy developer community by
the time it actually acquires non developer users (and quite a few of
our features never actually get out of the hobby project phase).
