I know that it has been discussed several times, but I don't agree this
is the right solution.

That forces smtp-forward to be the last plugin in the rcpt hook, because
any later plugin could return a 5xx (or worse, a 4xx) error to the
client while the backend has already accepted the recipient.
Since a large percentage of the recipients doesn't exist IME, the check
for existing recipients should be (one of) the first, not the last.
