I don't think any technology ever really "dies" CVS included. There are shops using perforce (a proprietary centralized version control system) as their SCM. It is true CVS is less popular in open source, but I think that has more to do with code hosting providers either not supporting it or dropping support (BitBucket dropped support some years back).
