Thatʼs a different branch of the startup logic :-)

If we change things so that ~/.emacs.d/init.el is used only if there
is no .emacs, they would not be affected. I think this is already
the case, but I may be misremembering

Iʼm not proposing changing the sequence, only what happens in the case
where there are no init files at all. It would eliminate the 'why is
emacs creating .emacs.d but then not using it' confusion.
