Same here, assuming what user use hardware for is a big mistake. 
Breaking
existing and established use cases is an even bigger one.

FreeBSD may be a bit silly at times, but their POLA policy is actually
spot on.

I also petition to revert this, or to make this a sysctl knob that 
defaults
to disabled so at least people that do want it can at least turn it back
on and have to do so knowingly.

Some of us don't really have a say in what security products our 
employers
choose, and we'd like to continue using OpenBSD.
