I disagree.

I think that glibc, of all places, must carry the burden.

There is a certain notion of consistency that must be kept across all
ports, even new ports, to make it easy to build a large collection of
userspace applications (see Chris' comments).

My feeling is that If we want to remove sysctl we need to do so with a
cohesive campaign of communication that involves all the distros and
follows a well documented process.

I would be happy with:
* Adding sysctl that returns ENOSYS
* Mark it deprecated.
* Install the headers normally.
