These links have since been brought to my attention privately:

http://openbsd-archive.7691.n7.nabble.com/Scrub-reassemble-tcp-td259581.html
https://marc.info/?l=openbsd-misc=126344466917828=2

So despite the small benefits, it is better to just not use the "tcp
reassembly" option at all.

Perhaps a pf.conf man patch could mention the potential of window
scaling incompatibility even if I have had very few if any issues with
other devices?

Thanks for sharing.
I’ll re-use this at home.
