In this context I think it's wise to be on guard against perverse incentives and externalised costs.  There may, for example, be significant financial incentives to introduce a "fast lane" for Internet subscribers which is somehow "endorsed" by a standards body.

I think the IETF is in a good position to resist such charms, but as an industry body the 3GPP might not be.  If the latter is taking their initial cues from the IETF, we need to be sure that they will also respond appropriately to an experiment termination.
