In an ideal world, part of a good change-management process is to notify
those who may see differences as a consequence of any proposed change
(tell the folk that care). That way, they know something is moving and
can plan accordingly. Also they can advise in a timely fashion if it
either works or not and make their own changes when appropriate.

Sadly, we do not live in an ideal world :-(
