Implement the Mollweide projection. As of version 9.4 of EPSG geodetic dataset, there is no known EPSG code for this projection. Formulas can be found on Mathworld or Wikipedia and (unofficial) parameters can be found on GeoTIFF list of projections.
Improve CRS.suggestCommonTarget(…) by allowing to know Set<FunctionProperty>
Allow derivative to be specified by the inverse projection instead than the forward one
