Yes, it does come from me, maybe we're talking at cross-purposes or
maybe you're out to yellow-snow wash me ;-)

The report does try to explain, there was no obvious way apparent to 
split
the spec in terms of shells or layers of complexity, as with SVG or OWL.

There was merit seen by many for 'domain specific' profiles, though
there was general discomfort for these to rule out or constrain parts of
Schema, only identify which parts are likely to be widely supported by,
say, data binding tools.

Given your strong and interesting views on this subject, it's a shame
you weren't able to attend and stop what you see as 'group think'!
