Such an approach at least worked well for OWL until now. A few competent
people just started to work on a draft, not constrained by any formalistic
processes, providing to the community a set of concrete new features to be
discussed. Others are discussing the different proposed features
controversaly, again others include experimental support for these features
into their tools, so that again others are able to play around with it and
report back problems. The now started WG will find a good foundation for
their work from the beginning. Certainly, a few things will yet change or
even be dropped, but other proposed features seam already to be widely
accepted, and are even already in use, due to the rapid incorporation into
existing tools and reasoners.

Oh, does this mean that there would be no place for heated discussions about
Reification/NamedGraphs/Quads/K-Tuples? ;-)

But, seriously, I like the idea of rapid incremental updates (i.e. "1.1") to
RDF. If there are features or changes, for which there is already common
consensus in the community, and which happen to be only "conservative"
changes, then it is probably better to put these feature into a standard
soon, instead of waiting another five years or more for a "big next
revision". The longer one waits for such changes, the harder it will become
to introduce even slight changes into the standard, provided that RDF and
the SemanticWeb will (hopefully) become more and more "mainstream" within
the coming years.
