In my opinion this is unnecessary for small teams, and doesn't scale to big teams.

Either your team is small enough that this should just be a conversation you have when you'd rather team members change their behaviors - OR - your team is too big to read and remember everyone's preferences.

Also, at the end of the day, the two people trying to communicate are either going to have similar preferences (Both morning people, both prefer talking over real-time video chat, etc), or they're going to have vastly different preferences (night owl, prefers async communication, etc). These user guides don't change anything in either situation, the person with more leverage is most likely going to "win" any decisions over how something ultimately gets communicated.
