    RFC 7370 created the registry by merging multiple existing registries. 
    It did not really defined any new functionality.

    We are changing the name of that merged registry. Given that RFC 7370 
    did not define anything new, just defined the merged registry, one can 
    consider the name change as an update to RFC 7370.

Ok - I missed that. I agree with that it updates RFC 7370 since the registry name changed as opposed to simply adding code points. 

Thanks,
Acee

    thanks,
    Peter
