10 years? 20 years? This address format is out in the wild for years
now. Lets look at an example: changing the IP address formats defined
in RFC 6991 (published 2013, updating RFC 6021 published 2010) would
likely be a non-backwards compatible change and thus all YANG modules
importing from RFC 6991 may need updates and then these updates need
to be implemented and finally shipped and deployed.
