Because it causes that same undesirable loss of symmetry you mentioned
about MCVersionName and String, except much worse because it's in a more
general sense instead of application-specific.  It makes headaches for
Magma applications because client code has to be aware of it.

Smalltalk wants to be about messages, not types.  What do we need to do to
make #class non-inlined and therefore overridable?  My impression is that
this is on the table for 6.0, is it still?
