Well, the machine tried (and failed)... and a quick search comes up
  with <https://marc.info/?l=netbsd-port-i386&m=109042024503576>.

kernel core dumps to swap on RAID 1 sets should be working. If they arn't, that's a bug. (initial implementation was in 2007, with some fixes in 2016... but perhaps crash dumps to RAID 1 swap isn't as widely advertised as it might otherwise be...)

Later...
