I believe, with you, that there's likely to be a time when unauthenticated mail simply will not be delivered by most receiving domains. I similarly believe (as the owner of a Tesla) that there will be a time when cars will be self-driving in the vast majority, and that that will make the roads both safer and more efficient.
Neither of those situations is here yet, though, and neither is likely to arrive very soon. Some day, yes. Not yet, and not soon. While we can certainly discuss the former -- particularly with a focus on what needs to happen before that situation can be realised -- we need to first make sure that we resolve the few remaining issues in the DMARCbis and reporting documents and get them published.
