Thank you. While I don't know why emulators/wine was never functional, I have additional comment.
I noted in your reference:

On most architectures, the FreeBSD kernel splits the process virtual memory address space into two portions: user and kernel.

My recollection is that on OpenBSD kernel and userland address spaces are separate. I could be wrong, of course.
And, with the singular exception of securelevel(7), OpenBSD doesn't have security knobs. You will find there is no security.* branch of sysctl settings as there is in FreeBSD, for example.
