Subject Re: Physical Operator Tag Change (SPLIT -> REPLICATE)

I agree with you.
However, can you have two separate changes:
1. Your current change  Call
your "Split" "PartitionSplit" for now.
2. Do what you proposed in the next change which only does the renaming.

That makes reviews less overwhelming and easier.
