I think it's great! I'm planning on trying it out on a few things and I'll let you know if I have any suggestions. I _almost_ suggested Proxy earlier, but I had never used it and I wasn't sure whether it was appropriate for the problem you were having.
I would be glad if you will do this. :)
Overall, I think a lot of people will get a lot of use out of it. It's something I know people have been looking for, but I think you'll have to save the link and when someone asks/talks about NonNull references/pointers you can refer them here.
That's a good idea.
