Hi there,
The readme says this library is based on 4122 which is obsoleted by 9562. I compared the two RFCs and found no significant diff between the two. I checked briefly and only parts related to v7. Do you have any comments regarding this:

1. Does it matter which RFC we're talking about in this context? (At least for V7)
2. Any plan to change the underlying RFC to 9562?
3. Is it safe to use the current version of the library which is based on 4122?

Thanks.
