Hi, Owen, I take this as much more useful discussion than bit availability. I share your opinion that ISPs should be much more carefully as their will be consequences for downstream customers, comparing to enterprise. These will be included into the future version. :) As a neutral analysis, it is fine to say there are benefits and pitfalls. All good things come with costs. I will make sure we document both sides in the draft.
