Seems to be a wrapper around implementing the "index into data store"-pattern (not sure if there is a better name), but without support for removal from said data store.

From a quick glance I don't really see what this gives you that wouldn't also be quite easy with a manual implementation. And then you avoid the proc macro compile time overhead as well.

It gives you more type safety, because you use a ProxyᐸFooᐳ instead of just usize.

In my manual implementation I would assume you would use a newtype, so not really relevant.
