just an idea that crossed my mind when i read this posting:
stability of GO IDs is for many applications very useful. thus when the
definition is improved, but still describes the same concept, it would
be nice if the concept could still have the same old ID, or that it is
possible to see at the ID that it is still the same concept.

this could be handled if GO IDs would be extended by some "versioning
extension", for example  GO:0004534
could become
after a first revision and 
after a second revision and so on...
