Don't be sorry, I'm glad it was stated.  That's good ground for
discussion.

Yup.

monotone update -r h:c:levitte-tested=1

(that basically mimics the approval functionality but with a private
cert so as not to intrude on others)

OK, so nothing stops you from having a B: that mimics h:b:.  The
question I have is, why limit it to branches.

And if 'h' doesn't sound right to you, what letter do you propose?
(oh, and please, anyone with an opinion is welcome to contribute!)

At this point, I'm wondering if it's the functionality or the letter
you don't like...

Nope, just the address@hidden argument :-)

Well, h: (or whatever letter you want there instead) is actually a
permanent solution that works, as far as I can tell.
