Be able to opt into old style with config options, which would enable outputting either fully GeoJSON2008, or opting into or out-of individual RFC features (eg. fully RFC-style except using an alternate CRS, or skipping antimeridian-cutting). These options should enable people to migrate systems gradually. The above doesn't do good things for GDAL backwards compatibility though :) Cheers, Rob.
