Yes.  And a more general solution (or set of solutions) is needed.  The
biggest problem with implementing any solution is the inadequate way that
coordinate systems are referred to in GRASS.  This, unfortunately, affects
more modules than those specific to projection (and that's why it was put
off to 5.1).

Personally, I'd rather not see another partial fix get stuck into GRASS.  But,
I'm of the opinion that a general solution cannot be cleanly implemented until
the "system" for specifying coordinate systems is cleaned up, and itself
generalized ("Unknown/X-Y", "Geographic", "Projected (inc. Geographic)").
