Hi Steve, moving the discussion to the geowebcache-users list as the topic's gonna be of more relevance there. Still cc'ing the geoserver-users list for this last message though.

I say semi-official, as the > State doesn't care, but we do. sounds good to me, as long as there's more than one "entity" using it. What about we start with a wiki page [1] where we start collecting these gridset definitions so that they can be easily shared with others and we include them in future gwc releases? Sounds like a good idea? Note GridSets have a "description" attribute now, so it'd be good if these shared gridset definitions have a description of its intended purpose, audience, author, whatever is relevant. Some examples from the WMTS spec: GlobalCRS84Scale: "This well-known scale set has been defined for global cartographic products. Rounded scales have been chosen for intuitive cartographic representation of vector data. Scale denominator is only accurate near the equator". GoogleMapsCompatible: "This well-known scale set has been defined to be compatible with Google Maps and Microsoft Live Map projections and zoom levels. Level 0 allows representing the whole world in a single 256x256 pixels. The next level represents the whole world in 2x2 tiles of 256x256 pixels and so on in powers of 2. Scale denominator is only accurate near the equator." GoogleCRS84Quad: "This well-known scale set has been defined to allow quadtree pyramids in CRS84. Level 0 allows representing the whole world in a single 256x256 pixels (where the first 64 and last 64 lines of the tile are left blank). The next level represents the whole world in 2x2 tiles of 256x256 pixels and so on in powers of 2. Scale denominator is only accurate near the equator." and so on..
