Ok. DavidH is on vacation, so I just picked that up directly.

I'll let this be for now. It's more of a "don't do that then" thing,

This seems to be a "damned if you do, damned if you don't", in that
different versions of libtorrent seem to expect different behaviors.

I think we're leaving it be, so that there's just one behavior going
forward, rather than vacillate between two and making things just
worse and oscillate depending on which one people use.

Not good, but there doesn't seem to be a good case.
