Uh, that breaks with the original goals of Schema.org somewhat ??... having
a unified, agreed upon, schema (instead of everyone sorta doing their own
thing and not having agreed upon types and properties)  I wonder what that
flat bag of types would look like ?  Perhaps your thinking more that flat
bag of types should be flipped around to Predicates themselves ?  Like
something like Freebase's predicates, "abstraction of", "abstraction",
"part_of", "parts" ...
https://www.googleapis.com/freebase/v1/search?indent=true&help=predicates
but you still need basic types to hang a Predicate off of.

One of the "nice things to have" is that Schema.org PUBLICLY helps bring
agreement on Types themselves.  I would not like to throw that out.

Then you'll need to be a little more clear...do we need a looser schema ?
or only in some places ?  Remember the original goals of Schema.org and
what we were trying to solve in the 1st place.  (Freebase created higher
and higher kinded Types, but eventually you reach a plateau of sorts...
I.E. We cannot just have Thing only in that flat bag. :)

Yeah, we know reality, Martin, and you and I agree a lot on that reality in
the past :)   Hmm, perhaps I am just misinterpreting your global view of
things for the future of Schema.org  ... can you elaborate more or blog
about your flat blag of types idea ?
