Thanks Joe, I missed it :-(
But is there any justification for this or is it planned to handle
annotations on type use when selecting processor?
It should be possible to do that as I showed with the draft I posted yesterday.
Using "*" means that processors focusing on type use are always run
which isn't what we'd expect and not optimal in performance terms...
