Yes, this is something that is often discussed with other maintainers.

Patchwork delegate requires to maintain a map between pw logins and an
actual mail address (if we go with email for the second point).

I'd vote on any maintainer from MAINTAINERS, _but_ it must be from the
files in the repo, not in the series being tested.
So maybe the easier is to have an explicit list... ?

Just listing this option for discussion, but this is dangerous, as any
user could then call reruns.

While the postal letter has its charm, an email on the ml is better
than pw for me.
It leaves a trace on who asked and when.

And I am not sure how you could trigger a CI rerun with patchwork anyway :-).
