A simple result of the fact that FSF stopped working on SCCS.
I don't think the FSF ever worked on SCCS. James Youngman has implemented CSSC though, which aims to be compatbiel with SCCS. I don't know what status it has and the only real use I think is to retrieve SCCS-code from the respository and put it into some better revision control system.
Over the past few years I've heard several times that people are working on various alternatives to CVS, but I don't think the FSF has ever been involved in either of them. In the end, it's simply a matter of what the various GNU volunteers wants to do. The FSF has no magic pool of money they can use to hire tons of developers for specific purposes :-)
