I not keen to see the limit reduced, but perhaps advice to clients to
default further below 100 than they may doing already may be warranted.
I can only speak to Postfix, which defaults to sending up to 50 and
accepting 1000.

I would like a requirement that servers must not reject the entire message
if there are up to 100 RCPTs even if the server returns 452 for some of
them. Senders can then pipeline safely.
