Um, things in pkg are independent packages that are not necessarily being
versioned at 1.0, so it's not necessary and may not be appropriate to remove
things that they deprecate. This CL sounded like it was fixing things in pkg

things deprecated in the packages.

That being said, this says it was to be removed some time ago, and it's
perfectly reasonable to do it.
