RFC-4 has already been discussed on the psc list, http://lists.osgeo.org/pipermail/geomoose-psc/2012-November/000058.html so I renamed this RFC-5. I will make appropriate changes in the patch too.
Also note that RFC-3 has a status of development so it has not yet been adopted and is not in effect and could change.
I'll get this committed by early tomorrow. There is no requirement about who starts discussion on the list, calling for a vote is likely to be done by a PSC member and only after two days after notice of the RFC on the website.
