It adds a bunch of ancient-compatible ioctls to the kernel.

It is, as a principle, not needed, but thanks to the many variants
of "sh configure" employed in usr/ports, a quite large number of
ports go "Ohh, this is BSD, I'd better use the old ioctls" and
break if you don't offer them.

Never attribute to malice what can adequately be explained by incompetence.
