Review comment:
These are independent ways to configure the overwrite. There is no
guarantee that checking the delete filter will also check the specific data
files that were deleted.
I agree with you that when we call `validateNoNewDeletesForDataFiles` we
should only pass the actual conflict detection filter and not the row filter.
That row filter may not be relevant for the deleted files.
