That is a nice one!

Mine is relying on bash_completion to look up potential hostname from
the ssh know host file.  Using <TAB> I can look it up:

 ssh foo<TAB>
 ssh foobar.project.eqiad.wmflabs<RETURN>


OpenSSH hashes the hostnames in the known_host file though so one would
want to disable that feature in ~/.ssh/config

   HashKnownHosts no


Obviously, one might want to install bash_completion and source it from
its ~/.bashrc .
