According to the ChangeLog, this was added to Tramp in August 2002. I
don't remember a public discussion about, it was just agreed between Kai
and me.

Don't know. Likely no problem, because

(file-name-directory (directory-file-name "/ssh:host:"))
=> "/ssh:host:"

Perhaps it is a good idea anyway, to add a regexp matching "/ssh:host:"
to locate-dominating-stop-dir-regexp.
