Emacs Starter Kit

Phil Hagelberg has started a starter kit for Emacs development. I wonder if I should polish up my setup and publish it in some way. Some things to consider are:

1. I would need to separate my work-environment-specific customizations from general use.
2. I have my own personal Git repositories for maintaining copies of my Elisp setup on multiple machines. How does that mate with publishing those files elsewhere?
3. ELPA is in use for some packages I import, but others I've checked in local copies of that are not in ELPA.
4. Would it be better to contribute to Phil's code base or go it alone?
