Even if you think the proposal is broken the problem is there
and needs resolution, not aggravation. 

Re initial proposal being broken I admitted it in the comment.
We'll have to do an incompatible change and violate ANSI - in
order to make the product usable. I suggested to add a
case-insensitive unique index to every system space already.

As to the suggestion being broken - it will allow one to get rid
of uppercase-before-store and be mostly ansi compatible.

It's less broken what we have now.
