See, I can ask them, or better, "advise" them, but I can't actually
rely upon them, can I?  There is still a chance that the user lacks
this setting, or (even worse) has it wrong, isn't there?

If Emacs set "EMACS_EXE_PATH" for me, I would not need to advise my
users to change their "init.el" (at least in foreseeable future), and
there is little chance that things can go wrong.

Surely, it is not essential, but it is *a lot* more convenient, if
Emacs just got things right here :)
