Those are good technical arguments.  However, if one views Mercury
users as "customers," I think one must be careful about the mental
model they develop of how the Mercury system is evolving.  If you're
going to just yank support (which I agree is technically a sound
idea), I think you should include a message reaffirming the usual
policy of warning before removing things and explain why you have not
followed that policy this time.
