I don't understand what you're saying.  The auto-mode-alist's purpose is
not "to avoid byte-compiling" but to indicate what kind of content is to
be found in the file.  And all I'm suggesting is that we should take
advantage of that info in more places, for example when we decide
whether to byte-compile something.
