It would be great if Typeclasses Opaque supported explicit Local and Global just like the underlyin

This is very low prio, but it usually happens that when touching Prims or some other file high in the dependency graph, we get spurious diffs in many other files. Since we check-in the snapshot, and we need to have it up-to-date, we get very verbose commits when nothing relevant changed. Plus, when something did change, it's hard to spot.
