It's not an RFC, it's an Internet Draft (which anyone can submit without review), and anyway it's offensive and incoherent enough that nobody will take it seriously, and it certainly won't make it as an actual RFC.
Why is it offensive? How is it incoherent?
The proposal is needlessly complicated, notwithstanding the poor quality of writing. The authors' rationale is to "realize autonomy", yet AIP suffixes are globally namespaced and still need IANA assignment, which is really no different to the current situation in relation to TLDs. It breaks backwards compatibility when applications need to cross AIP networks and also introduces the issue of conflicting AIP network-internal names. The authors make no attempt to discuss these obvious issues or any others, and also blindly wave off security considerations, saying "there is no additional security requirement".
Also, the authors are on Yahoo/QQ free webmail addresses, which isn't very professional.
