> Right now a RegionObserver can only statically implement one or the other. In scenarios
where we need to work sometimes on the single postPut and postDelete hooks and sometimes on
the batchMutate hooks, there is currently no place to convey this information to the single
hooks. I.e. the work has been done in the batch, skip the single hooks.
> There are various solutions:
> 1. Allow some state to be passed _per operation_.
> 2. Remove the single hooks and always only call batch hooks (with a default wrapper for
the single hooks).
> 3. more?
> [~apurtell], what we had discussed a few days back.
