In that case, I will "upgrade" my Ack. ;)

While I'd like to have published guidance on fixing existing language
(which is already underway[1]), I agree: let's start here.

the main and primary should be merged, IMO:

	'{primary,main}/{secondary,replica,subordinate}'

leader/performer does not track for me. Split it out?

	'leader/follower', 'director/performer'

I have also seen:

	'controller/worker'
