My previous response was not really clear on how I feel.

obviously has to include multi-geometries.)

I've implemented a GeoJSON RESTful server. It maps JSON into KML,
GeoRSS, GML/WFS, and the OSM file format. It doesn't have multi
geometries. It lets me scribble on a map in OpenLayers and save the JSON
data to the server.
It does pretty well. It works. And it has no support for multigeoms.
This is not a 'full' mapping of every possible type of data: it's a
description of data along the lines of what Google's "My Maps" service
can handle.
I think this level of functionality is extremely useful -- it's
translatable to many formats without the need for the full support of
GML and multiple geometries.
So, I feel that:
There should be a 'simple' conformance which does not support
Multiple Geometries. This simple conformance only requires support
for Point, Line, Polygon, Box. (I'm unconvinced on whether polygons
need to support 'holes'/multiple rings.)
Then, I think a second level of conformance should be created, which
includes the functionality just described in the RFC-001 wiki page.
IN other words: I'd like RFC-001 to go back to what it was, and RFC-002
to be created with what RFC-001 currently is.
