I'm fine if we don't mention NPT in the draft.

If we are going to mention NPT, then I will strenuously object unless the draft also contains language specifying that any form of address translation is not recommended.

Configuring BGP for PI would not feet all the users, especially the small enterprises and home users. And needs no cost on RIR fees. Moreover, no limited PI might potentially cause serious BGP4 scaling issue, considering the multihoming requirement in IPv6 might explode.
