I think there's an underlying discussion about naming convention here.
 You said you wanted to leave it out of the list, but it is central to
your argument.  I try to keep a purely pragmatic approach, but when
you say "using this name may work well, but it is wrong", then we have
to argue about what is right and what is wrong, and we can't have a
pragmatic discussion anymore.  It has become http://tinyurl.com/qysbk
already.

It is a timing issue.  I don't propose that the macro is used _before_
it has become appropiate to use it.  A several year period would be
necessary for 3rd party software.
