What feedback was there that seemed insurmountable? Last I talked to
Jeff Cody he said there was no "overwhelming pushback" against his
patches, just a list of concerns.

This doesn't sound like a dead end so much as it sounds like we haven't
planned the feature enough yet.

I think this is being unnecessarily hasty. We should make sure that an
auto-generated ID system does not create problems for other areas of
code before we rush ahead with one to solve a single problem.

Let's give the universal approach some more time before we jump to the
conclusion that it's impossible.
