Yes, I will.

It turns out that the methods I am removing are ones Ken added - they can
be kept for a release, but the behavior will change. I doubt anyone else is
using them, but if they are they should be able to do what they want using
a different method.

This is convenient - it means I won't break any regression tests!!! :-)
