That's what CheckedInt is for, and that's what we use. The problems webgl deals with aren't arithmatic. Arithmatic is easy. (CheckedInt!) Reasoning about constraints is hard.
We have some entrypoints where negative values are valid, and many where they are not. It's really nice to have a natural way to document which we expect /at compile time/. Saying "no unsigned types" really throws out the baby with the bathwater for me.
