Yes, but the reason we did that was that we did not want a vanilla Emacs
to load Tramp so eagerly.

Very few people will disable it (it's been tamed specifically to that end).

Sadly my reader is out for lunch, can you help me understand how that
would work?  What kind of interaction do you expect?

I was originally thinking that we could use partial-completion here.
Basically, just like "/u/ TAB" can try to complete to /usr/ (after
checking that there's no /u), we could have "/s: TAB" try to complete to
/ssh:, but there's a problem: we'd need to "check that there's no /s",
which in our case means check that there's no host named "s" (since
/s:filename would refer to a filename on host s).  If we get rid of
ange-ftp's /host: syntax and force the use of something like /ftp:, then
maybe we can get something working.
