This to me implies that no new features can be added, since they
automatically have not yet been implemented.  E.g., precisionDecimal
must then wait for 2.0.  I don't think this is what people want.

If an existing feature has not been implemented across the board,
perhaps it is not that it is inherently too complicated, but that we
did not describe it properly.  Seems a shame to rule it out then.

I thought one of the purposes of 1.1 was to better describe the
features so that incompatabilities between implementations could
be eliminated.  This seems to make more sense than simply saying
"if we didn't get it right in 1.0, it's obviously not useful and
hence is hereby deprecated".
