Hm... it's a pity that SSH is special. Can we not abstract fro the
actual communcation media and protocol? I mean, "ssh foo", "rlogin
bar", "telnet baz nnn" or "cu system" more or less all do the same
thing: setting up a communication channel.
I would find it really nice if we would leave the decision which
tools [cu, kermit, minicom, ...] / media [serial, TCP/IP, CAN, ...]
/ protocols one wants to use to the end user, without needing to add
specific code for each of these.
Is this possible?

Well, the BDI connection would use "telnet" protocol so I don;t
think this is related to the sshd configuration?

This is what I mean: I don;t want to add gdbserver or BDI support.
I just want to have the ability to connect myself to such tools.
Actually I have no idea what else one might want to use - but I can
come up with a pretty long lsit - more tools / types of coneections
you ever want to implement as special cases :-)
