And it will still be available. It'll just be available in the Attic. The
fact that it will get more broken in the future because it's not being
maintained in the tree is not terribly significant since it's already
broken now.

There is at least one, namely that it will make kernel code updates easier
to do, and easier to test.

Your argument here is non sequitur because we still have large bases of
users and developers that have and use this hardware. I retired a box with
an original P90 f00f bug cpu not that long ago, for example. netns has
neither freebsd users or developers, and hasn't for years.

I think that fixing the current brokeness is still useful, even if it gets
axed. Putting it to bed with a full tummy will make future educational
value of the code that much higher.
