Why not have the default configuration set to use them?

I have heard this for years, and only a month ago learned why this makes more sense than the 100 other options:

config management and deployment tools all know how to manage custom environment vars and because everything can use them there is lots of development focused on that. 

As opposed to Carl's nifty config.py that is a bunch of dicts that I edit by hand because no one has built a tool to automate it.
