Two former PR's (keys, trusted keys) look a bit different as I realized
that my current script does not scale too well. So I do in future use
a method where the subsystem name is picked from MAINTAINERS and I have
crafted aerc templates [1] for each subsystem (also CC lists need
tuning).

This will get better and more polished as I get my scripting more
polished. If anything went wrong, it is mostly because process changes
have their glitches :-)
