I think that there are indeed other problems that would make a larger
difference[1,2].

But the question the ".el8" proposal was supposed to answer was "what if
you really don't want to decide this issue based on the contents of the
file", which means it needs a new suffix since it's a new file format.
If you stick with an already used suffix, you can still assume things
about that file, but you'll have to check and backtrack if that
assumption turns out to be wrong.  These checks could easily nullify the
effects that one was hoping to have by making the simplifying
assumptions in the first place.


[1] Being able to use a "byte-compilation-server" instead of having to
start a new Emacs instance for each byte compilation.

[2] A mode of compilation that ignores ".elc" files in the compilation
directory, at least when they are older than their source, like any
other compiler would do.
