It's a technicality, but I believe an important
one. There has never
been such a thing as a 'community de-sysopping' and creating such
might be problematic.
If we were to institute such a thing, I believe it should be done with
a bit more thought and discussion.
This is the kind of thing IAR is for - so we don't have to come up
with detailed new rules to deal with situations that virtually never
happen, we can just do the obvious thing and be done with it.
