My wish is for (SMTP) servers to support higher levels of group sends

Any SMTP Servers that do otherwise?
This seems like a configuration choice and hence up to different service
providers. I'm unaware of any SMTP servers with built-in limits. Mine
doesn't. From an SMTP perspective, the various message header fields are
irrelevant to the SMTP protocol (aside from trace header fields); there
is no difference at an SMTP level between 'To:' addresses and 'Bcc:'
addresses.
It's always risky to use the 'Bcc' field, though, because it's too easy
to accidentally put the addresses in 'To' or "Cc". It's generally better
to use a mailing list. Many SMTP servers support their own crude mailing
lists (simple address expansion) and of course there are many mailing
list servers available, such as Mailman.
