The most current upstream bug for this is probably either
https://bugzilla.mindrot.org/show_bug.cgi?id=3048 or
https://bugzilla.mindrot.org/show_bug.cgi?id=3470, and those explain the
historical reasons why the design is the way it is. I don't think
there's anything we can sensibly do in Debian about this, so I'll just
mark this as forwarded upstream.
