Syntactic nit: that would be file:/path. If the leading characters after
the scheme are not //, then no host is present.

To answer your question, here is a practical example:

OpenCM never got our network connection stuff working satisfactorily.
More accurately: we never got GC debugged correctly. We ended up with
many repositories at /home/OPENCM. These were named by file: URIs.

It was pretty easy to attempt a commit in the wrong place. This would
fail, but mysteriously. When we added the code to "check host name if
present in scheme", a lot of mysteries went away.
