That is, instead of having to list out all the various SNI hostnames that a cert should be used for (e.g. "local pop3.example.com (http://pop3.example.com) imap.example.com (http://imap.example.com) pops.example.com (http://pops.example.com) pop.example.com (http://pop.example.com) .... {" -- and on and on), it'd be handy to be able to just say "local *.example.com (http://example.com) {" and call it a day. I imagine there'd be a bit of a slowdown, since you'd have to loop through patterns on each connection (instead of what I assume is a hash lookup), esp for people with significant amounts of 'local's.

Actually that is supported, but you need to use v2.2.35 or later.
