There is really no choice. vt(4) will work as a basic console on all
platforms. sc(4) works on old hardware, but not on an increasingly large
portion of "modern" hardware. Since being able to boot on most hardware is
critical as well as supporting non-CP437 languages. It' pretty much a
no-brainer. And, since switching back to SC(4) is trivial (add
"kern.vty=sc" to /boot/loader.conf), I believe any other option would be
It is important that the release notes for 11 clarify these changes and
make it clear how to switch.
