Although blueprint implementation seems to bring much desired sharing of people’s ideas on how to do automations, it is not always effective. This is simply because middle ground between no power and too much power to the user is hard to deliver and, in the end, it only creates confusion for the new joiners.
As many users post incomplete settings or they are failing to reply on previous comments, a curated list of blueprints would ensure only higher quality items are getting through (or, at least, the ones highly voted).
