The IETF is about engineering and sometimes, hopefully often, that will provide a solution. But there is always the alternative of a business solution which may override engineering, and that is something that the IETF should stay away from; it lacks the skills in that field. There has been a lot of business/economics in places such as the RRG and what I see is the IETF (or IRTF) lacks the skills ever to achieve rough consensus in that area.
So the onus is on operators to turn their good business reasons into engineering problems, eg as a requirements RFC, that the IETF will then solve.
