That agenda and draft seem to make the seemingly common enough mistake of only focusing on what a new privacy or security mechanism breaks and glossing over the good reasons why people introduce these mechanisms. I hope the BoF proponents fix that because otherwise they may end up giving the impression that they would prefer to not see the privacy benefits (which I'd guess is not their goal at all). One reason those good reasons need to be included is that they constrain the kinds of additions that might make sense to better handle the new mechanism.
We've seen a number of these kinds of reactions and I figure it'd really be better if the reaction were not to appear purely reactionary;-) If that were fixed, then there may be a better discussion of what, if any, additional things need doing. If that is not fixed, I'd not be surprised if the putative BoF were to devolve into a "it's bad" vs. "no, it's good" bun fight that won't really take us further. Cheers, S.
