I don't agree here. Such a feature is already present in gschem.
Symbol versioning is aimed by the symversion= mechanism (see
http://wiki.geda-project.org/geda:master_attributes_list#symversion).
If you make some major changes in a library symbol, your projects
can be damaged by that if you do not carefully verify them, e.g.
if you change some pin positions. Minor changes (graphical,
hiding/showing some attributes and so on) are always OK.
