After JDK-8219613, there is only one remaining use of a shared dirty card queue. All other uses of dirty card queues are thread-local in one way or another (in the G1ThreadLocalData, or in some local object such as a G1ParScanThreadState or a thread-local closure object).
That remaining use (in G1RemSet::refine_card_concurrently) still needs a shared queue.
However, having one class which supports both the normal thread-local usage and that one shared usage makes the code more complicated and less performant than need be. The shared case should be separated out into its own class.
