   You are the first person to say that `invocation-name' is important to
   keep.  Would like to expand on the use-case you have in mind, and why
   you think it is important to keep as the default?

I can think of one situation, when running multiple emacs:en of
different version.  E.g, development versions or when you wish to run
an older or newer version.
