In other words, how clear is it what problems need to be solved? In

that agrees that the problems need solving?

1) Per RCPT filtering is a request we (sendmail.org) get fairly
often. As it cannot be done "directly" in ESMTP (yet), people ask
for "wierd" workarounds that are complicated to implement.  Moreover,
I already see some workarounds being implemented at some ISPs (e.g.,
accept only 1 RCPT per transaction) as well as in milters.

2) The number of requests we get and the number of "workaround
proposals".

I keep wondering whether it isn't just as useful and far simpler to have an 
SMTP option that says "send addresses after content"?

No (see an earlier mail about this suggestion).
