If you hadn't seen it, you may find this recent discussion about sysupgrade informative: https://marc.info/?t=156851721400002&r=1&w=2

And yeah, you're right, even light criticism on the OpenBSD lists is met with a very strong and negative reaction. That said, I think improvement suggestions that come with a diff and a constructive attitude are generally well received.

Also sysupgrade is a pretty brief ksh script, so fairly easy to see what it's doing.
