FWIW, I am fairly strongly against that. Every extension author is
going to feel that their information is so important it should come
first. Other people might have a different opinion about that, and
in any case they can't all be first.

There's certainly room for bikeshedding here, but I think it'd be good
to get some actual experience before redesigning what you've done.
