But wouldn't processing the file in a "more literal" manner solve that
problem as well?  We only process file-local variables when we turn on
the proper major mode, so avoiding to turn on a mode will also solve
the problem you have, including unsafe variables.  And finding the
telltale signature of the file's encoding doesn't need any major
mode's help, does it?
