Oh man. This is one of those things that's great when done well and terrible when done poorly. Miss the head-up memo until the following day? Too late, the author's already a day into the work and you'd be a jerk to make them back all that out. If it happens often, you have to constantly monitor communication channels or risk missing an important "heads-up," since that's how serious decisions are being made now. In the middle of your own work, but see a 10-page design doc go by in slack or email? Better drop everything and read it well enough to form an opinion because every minute that goes by it becomes harder to object to that change. But, as you say, it can be a great way to overcome bikeshedding. It's a good way to speed up a ponderous decision-making culture. It works. Like a lot of organizational tricks, the line between use and abuse is something that simply requires judgement.
