It gets hard to hand-tweak to repair some glitch some where, and now there is *yet* *another* version tracking problem if you want to recreate a specific design. I'm more inclined to the idea of a generator script plus a rules data base yielding a library of static footprints. New design rules? No problem.. mkdir; chdir; execute script. Now you have a new static library. I'll admit that this has scaling issues at the enterprise level, but I think it scales better than on-the-fly generation version control issues.
