Sounds dangerous to me.  I often place init.el files into
sub-directories which require project specific customization.  You may
also want to look at (info "(elisp)Directory Local Variables") for
adding setting based on the working directory.

Indeed, I've recently fully committed to this approach adding Emacs to
the list of services started by my OS during boot (probably overkill for
most users and configurations).
