I assume that is beacuse you do not do heavy UI changes with your
add-ons. But I do.

And from my current understanding, it should be possible to create a
general UI overlay API, as it does not create security issues and almost
no stability issues. So even under the new rules, that should still be
allowed and thus should be given back to us.
