Ah. So you want to be the benevolent dictator who stifles creative liberty in order to protect users from themselves -- you'd rather not allow them to make all those horrible mistakes that they certainly can't help making when they dare to presume that they can improve on your work and/or make your code more suitable to their individual needs... (I'm joking, of course, but only because your reasoning is kind of amusing.)

UPDATE: Just one point to clarify my motivation in poking fun at your plan: In order to make modifications harder for end-users, it's normally true that you end up making it harder in general. If you feel that the benefit of centralized control will justify the cost of the added maintenance load, have at it.
