Er, *what*?  We're in mid development cycle, we are nowhere near
release.  When exactly would you have us make major changes?

In any case, what I understood Robert to be proposing was an add-on
feature that could be implemented in one datatype at a time.  Not
a global flag day.  We couldn't really do the latter anyway without
making life very unpleasant for authors of extension datatypes.
