The "change" was actually made a while ago, in 851ae058 (2020-07-03);
my pull request yesterday was just a patch to bring the implementation
into line with what the spec says.  It's unfortunate that we didn't
get a chance to debate this change in semantics at the time.  However,
I think that changing the SRFI to make maybe-let*, etc. compatible
with SRFI 2 again would be too much of a change at this late date.

I don't particularly like the empty-body forms of and-let*, and I'm
happy with how much simpler maybe-let* and friends are now with
those forms eliminated.
