Review comment:
Does this method need to be public? I'm surprised that it is given that
`applyEqDeletes` is not.
I also think it would be good to have a better name for it, if it does need
to be public. This is really just applying a filter, so I think something like
`keepDeletedRows` would be more descriptive.
