I don't know.  I asked the others on the call and the answer I got was
essentially "Just delete it".

I'm kind of hoping the others speak up.

I listed a couple of things when acking this patch. Being broken is
not a problem as long as there are users who care about it. What made
me think such users may not exist is that nobody ever complained about
those things until we stumbled on them -- I'm not insisting on
deleting this feature, just clarifying why I thought so.

Similar feelings here. On the call it looked like the feature was abandoned by
its creators, and it wasn't clear if the distros that had it enabled did so due
to reasons that still apply for future versions. Sending the proposal and
getting a feedback that there are users is one of the expected valid outcomes.

The real question is how well we want to support it. My understanding,
based on the previous discussion, is "as-is". That is we simply follow
the current "semantics" when converting it to using folios.
