I agree =pkg-4.1* also matching pkg-4.10 is a concern.

In that case though, it would change the focus of the discussion to how
* operator should work, not necessarily adding a new ~> operator.

I think it'd be okay to e.g. change the meaning and behavior of * in a
new EAPI.

It's unfortunate this is rather theoretical now.

Consider looking for some real examples, I believe this could really
help the discussion.
