And here's a use case where SET FILTER can be quite useful in a production
application. Let's say you have a form that displays account receivable
transactions for a customer (invoices, payments, adjustments, etc.). You want
to be able to display only open (i.e. unpaid) transactions or transactions
related to a specific invoice. The primary query has returned all the rows I
need to display for that customer. SET FILTER handles that quickly and simply
without the overhead of running another query against the main database.

something other programs didn't (and perhaps still don't) have.
