There's no use case for that. Or, let me put it differently. I think
there's no use case, with the current code, to read from a different
desktop file.

The use case for reading it from different directories is built-in in the
current desktop.el (DIRNAME is passed as an argument back and forth), but
the desktop file name is a defcustom'd variable.

So, if we were to support multiple filenames, it surely wouldn't just be
changing desktop-read to ask for the file name, but fully support multiple
desktop files everywhere. That's a feature nobody's asked for before, I
think.
