it's been quite a while (scala/scala#7430) since we re-STARRed
and the desire for it came up at scala/scala#7069 /cc @som-snytt
Adriaan suggested re-STARR-ing after the RC1 queue is empty, but I'd like to do it now, also. if nothing goes wrong, then no harm done, and if something does go wrong, we'll have bought ourselves more time to deal with it
