I do, occasionally. It comes in handy with some older hardware, and
in an emergency.
As computers with multiple processors became more common, large parts
of the operating system were rewritten to work both safely and
efficiently with multiple processors; however, there remain some areas
where more work needs to be done, and developers added such messages
as a reminder and a warning. Up until recently, plip(4) was one of
those places, but John Baldwin fixed this for FreeBSD 8.

If you really don't want it, remove:
from your kernel and rebuild. You can always load it as a kernel
module if you later find that you need it.
