Yes, we should change that to say '~/.emacs'

Emacs will prefer the XDG path if it exists and .emacs.d/init.el and
.emacs donʼt. Similarly Emacs will prefer .emacs.d/init.el if it
exists and .emacs doesnʼt.

If nothing exists, Emacs will create ~/.emacs.d, and use ~/.emacs as
the init file. We can change that to use ~/.emacs.d/init.el if we
want, people who already have init files will not be affected.
