Description

Continuation of parent.
We can also do this optimization for seek hints. This would allow filters and coprocessors to be more liberal with seek hints, as seeking when unnecessary is less of perf detriment.

It's not quite as clear cut, since in order to check, we actually do need to create the seek hint Cell. Then when we actually seek, we need to create it again. Need to test carefully.
