Review comment:
some comments here might be nice describing the context of this check.
The context includes that we pulled the candidate delete list prior to these
scans. Hence we only really care that the tableIdsSeen is a super set of the
intersection of the ids before and after. There need to be more words to
connect those two sentences....
