True enough.

Well, now you're adding a whole lot of maintenance effort to support
some quite-hypothetical users of a function we all agree is junk ;-)

I think we should either leave it be, or rip it out and be done with it.
I don't actually much care which (does anyone out there have an
opinion?). But a phased-obsolescence plan is far more work than it
deserves.
