Review Comment:
1. For example, you have 2 skipKeys and 10 nodes, in case of filtering on
remote nodes you send additionaly 2 * 9 keys and receive 2 keys and 2 values
less (but receive the same amount in case of insert only transactions). So, we
can't be sure about reducing network usage. I think, in the typical usage, on
the contrary, it will increase network usage.
2. Transformers can enlarge values as well.
