I was OK with having if-let and when-let, yes.

I think more than 2 alternative semantics is hard to justify, tho:
I don't even see a single use of and-let (other than in tests).

Yes.

I think we should drop `and-let` and make if/when-let aliases of if/when-let*
(or the reverse).  I think it could still be done on emacs-26.
