Of course not.  It can be changed very easily, and very few users if any
will suffer from it.  In all likelihood the only cases where this
occurs are interactive situations, and we've generally considered it OK
to break backward compatibility with "old humans" (as opposed to "old
code", where we usually try to preserve this compatibility) except for
specific cases where we think that it will inconvenience muscle memory of
too many users.

Let's get rid of this ambiguity once and for all, so we can move on,
instead of adding hacks to try and keep it alive even longer.

So I see another problem:

   emacs -Q
   M-x icomplete-mode RET
   C-x C-f /ssh:foo:/

and now suddenly it's signaling errors because it tries to connect to
`foo` even though I haven't requested any completion yet.
I think it should honor `non-essential' in that case and not try to open
up a new connection until I hit TAB or some similar explicit request.
