Is this actually documented anywhere?  Or is this another of our
"this-is-policy-because-everyone-knows-it's-policy" policies?  I know there
was a technical issue with removing pkg_*_rm functions way-back-when, but if
there's no technical reason why functions can't be deprecated, and we're just
clinging to policy in the name of policy, then I can't say I see the point.

And if this is such a bad idea, then can we get it in writing?
