It seems there are real users whose use of Rmail would not be with a
single device, reading from local storage.  I have to believe it, but
I am surprised becaause I don't see how that would happen.  Would you
like to tell me the scenarios of usage that you were using?

Emacs always reads or writes the entire file,
and does it in a way designed to avoid any chance
of half-written files.  Also, it has interlocking for
writing a file from multiple Emacses.  That applies
to all files, not just Rmail flles.
