You sound like a surgeon resisting a checklist.  "Sure I sometimes take out
the wrong kidney, BFD I'm smart I don't need that".  Power tools shouldn't
gratuitously force you to remember things a competent tool can easily
remember for you.  If refdes aren't gonna be unique then some other thing
should exist  that makes obviously distinct symbols unique.  I don't
remember what ugly thing gEDA did to me with duplicate refdes but I
remember it being bad enough I immediately added machinery to my setup so
it couldn't happen again.  Perhaps the sane behavior should be the default,
and "power users" that want something else can disable it.
