So, the question remains -- WAS there ever a reason /in fact/ for
non-keyed PFs?

I always thought the reason was so that you could remove the index(es),
by removing the LF member(s).

For example, the rule of thumb was that if you had to add a large batch
of records (say > 10% of the current # of records), it was faster to
remove the index, add the records, and re-add the LF mbr, which would
rebuild the index.

You can't remove the index of a PF.
