Well, as I said, I don't think I'd make use of them in the main XBetaa/BBetza universe. Allowing their use for custom moves, once that is available, is the furthest I'd go with it. The ideas I cited for specific symbols are just examples, which I'd (at least hypothetically) code myself and make available to others. Others could also assign different effects to a given symbol; unless something really catches on, there'd be no standardization. The symbols wouldn't be used as part of any standard description, but only in specific games.
