How about "it isn't user-friendly"? A user makes a connection to an ssh
server by host and, optionally, IP address. Requiring that every time there
is another server on a host a user has to add to his/her config file, then
remember whatever alias s/he chose is user-hostile. It's even worse than
that, because that config change has to be performed on every account from
which the user might be ssh-ing.

I'll grant you that the functionality is there, but a minor
backward-compatible change can make it transparent to the user.
