Our charter is expressed in terms of authorization for network access. I could see providing context about the quality of the Internet connection (a la BCP104), but allowing destination-by-destination granularity has some pretty significant potential impact; it will basically be giving the IETF's blessing to zero-rating, and in some markets that's a very contentious topic.

So, we need to proceed carefully. IMO, we don't need to provide a per-destination capability to meet the charter, and doing so could add significant risk to an already risky endeavour.

As someone who has pushed back on zero-rating, I certainly feel the same.

While the charter does mention capital-"I" Internet, other parts are expressed in terms of "limited environments", "parameters of confinement", and other phrases.  I'm perfectly fine with zero-rating being a non-objective.  =)
