This is my point that the regulators do have ligitmate concerns but are willing to be helpful without being prescriptive.  As a additional note I also recently met with the FCC folks including brother Eric Burger and they had similar concerns.

OK. That sounds promising. I look forward to seeing how it develops.

Creating a stable consistent experience several millions of times a day will not be a quick achievement.  IMHO, application of SHAKEN/STIR will be permissive in the early stages, and really needs to be married to outboard analytics which look at things like network calling patterns and permit/deny lists in order to be able to render more reliable judgements to the network (or a client application) with respect to relative trustworthy-ness of a call attempt.

The regulators have actually been quite helpful here. They are willing to eventually help with consumer education if the framework for display options is simple, and I also believe there are excellent opportunities for service providers to add value.   Sometimes choice is bad and confusing the consumer with different forms of UX could cause its own problems.  Its still early.
