I haven't read the patch. My understanding from the discussion is that it
would allow callers of the indexam to receive a hunk of index pointers and
process them rather than have to wait for the complete index scan to finish
before processing any. Is that it?

In general I think we need to be more open to incremental improvements. I
think there are several fronts on which we refuse patches to do X because it's
useless without Y and have nobody working on Y because they would have to
solve X first.
