I think the current location is fine. Vendor directories cause other 
vendors to not look in them.

Drop the *-supply and use 'unevaluatedProperties: false' at the top 
level. 'unevaluatedProperties' can see into if/then schema. That doesn't 
do anything yet as unevaluatedProperties support isn't implemented yet 
(but there's finally some work taking place, so soon).

Otherwise, pretty much looks fine to me. Some of the grf.yaml changes 
should perhaps be a separate commit.
