I think it would be a "2020 remote work" style revelation for many teams. Many teams thought remote work would never work out for them, but when they were forced to do it, they found it actually worked great.
That being said, I doubt many companies would ever find the idea tractable. So we should start with something simpler: you should never schedule more than 2 hours worth of meetings for your developers in any given week. And those 2 hours should be very carefully considered, such that they don't segment their day.
The amount of wasted productivity that comes from endless meetings is staggering. Not to mention the mental health hit of trying to do challenging knowledge work while having your day constantly interrupted.
