One thing I find useful about the current way is that I can use ~/.emacs
to carry out tests requiring (or facilitated by having) an init file,
without having to move or otherwise disable my actual init file
~/.emacs.d/init.el.  That benefit would be lost if the priority was
changed (or it would require making ~/.emacs the real init file and
using ~/.emacs.d/init.el for testing, which seems less appealing).
