      Today, GC barriers or BarrierSet are called explicitly around accesses that require specific barriers.
      It would be desirable if instead accesses are annotated with declarative semantics. Instead of calling different barriers on BarrierSet in different situations explicitly that makes sense for some GCs and not others, this new approach should declare what property makes the access special and let the API automatically generate the correct barriers.
