For myself I would be fairly confident that this is not going to change any time real soon now and I think that even if it were to do so it is likely to retain the original ProdID as an alias.

However if you were going to look it up yourself you should bear in mind that the way that it is designed is that the registry entries map the ProgId to the ClsId guid rather than vice versa and also that the ProgId is not guaranteed to be unique.
