It's only bizarre and sounds that way because you don't like the message.
They've been pretty consistent for many months now.
30% to 60% of people have been ignoring them. But, that's not the same thing.
This will likely be the same. Anyone using the honor system and ignoring that guidance isn't going to suddenly take this new guidance and change.
One real impact it might have though, people who do follow the guidance (who are also largely vaccinated) will have the community spread metrics brought to their attention. Before, we all have a tendency to assume everywhere is just like where we are. Now, those people will be reminded that everywhere is not just the same. If it wasn't already happening, I would expect this group to travel less to the areas of high spread. May not matter if others backfill for them. At least in the shorter term. Longer term if this never gets under control and is high spread forever, it'll start to show up as people avoid high spread areas.
Who wants to vacation where accident could land you in a ER hallway for hours because the hospital is full.
