Indeed we (CDI) do not own common-annotations.
That was the reason why the JSR-250 working group release a MR for it which did contain the changes we needed in CDI. So from our side (EE) all was fine imo.
It's just that the SE team didn't update the JDK to this official MR it seems.

What packages do you have in mind? We don't "own" javax.annotation and 
we cannot introduce our own priority annotation...
