As I said, I want to know if a file name is likely to represent a remote
file (in the Emacs sense you cited) or a file on a mapped network drive.

The reason is to avoid the time needed to access the remote machine. That's
the same reason that most of the above were defined, but they don't handle
the network-drive case.
