Emacs does have to move on and eventually remove stuff that we've
deprecated, and that's fine for most things.

But thinking about this a bit more, I agree with Drew here --
interactive-p is used too much in the wild for us to ever delete it.  It
should stay marked as obsolete, but with a comment saying "never delete"
or something, because removing it will break too much code out there.

For a perspective on deprecation (which mentions Emacs :-)), this is a
pretty entertaining read:
