I thought I saw a patch or feature for an sshd for
blocking max connections per client, max failed
authentication attempts per client, and/or max
authentication attempts per client . Does anyone know
about that?

Or do any less popular open source SSH servers provide
that? (Keep counter of connections, attempts, failures
per client?)

OpenBSD has an option using pf to catch bruteforce
attacks. You basically specify a limit on connection
attempts on a port from one place. When someone exceeds
those attempts, it adds them to a table and denies them
further access.
