Hello PHPeeps, There hasn't been much discussion around the proposed feature, and I've interpreted it as a good sign :P It is not a super important change but it has some advantages, it's consistent with the recent improvements to type variance and also with future ones. Also, it's hopefully not too hard to implement.
