It's been a long time but I'm pretty sure I've seen situations in which it made
sense for the recipient limit to be 1. For example: a special-purpose device

or anything for which it makes sense to insist that per-recipient errors get
immediately reported to the client.
That's really the realm of LMTP, final delivery, not relaying.
No, it's not. I didn't say anything about this being used for final
delivery. The point is that there are legitimately SMTP servers that
potentially accept traffic from the public Internet, that aren't
full-blown MTAs.
