The better method I referred to was the proposal to provide words that allowed 
the implementor to report which standards were conformed to including the 
revision used (similar to the method in the ATA standard). While it's not 
likely this would be quickly used, it could be handy for resolving 
interoperability issues and have significantly more meaning than "SCSI-3
