They do it anyway, with excess meetings and increased amounts of BS. Example: How many "check-ins" can you possibly need for a 3 person project? It is mentally draining for people trying to get real work done.
Right, I'm on one project right now that 3 meetings a week, and one of them applies to my work and it really could be an email. Every simple project I'm on I quote 40 hours, where I assume it'll take me an hour or two to do the work and the rest will be meetings.
