I feel strongly that the kind of people who identify the need to create a document like this are probably not the people who most need such a document written about them.
That is, in order to feel it necessary to write something like this, you must be a manager who prioritizes answering the question "what can I do to maximize the happiness and productivity of my direct reports," over "what can I do to ensure my own personal success, regardless of anyone else." Such a person is already going to do the right things, and is much less likely to be hard to work with.
The people who really need these kinds of documents written about them are the ones who are actually difficult to work with - but for many very good reasons, that won't happen.
I think the publication of these are offering others the opportunity to be introspective of their management styles. While the document I wrote isn't necessarily covering anything I don't already tell and re-affirm to my direct reports, it was a great exercise in thinking through my management style and what it means to me. I hope that the more popular these things become, further conversations can happen in the community to figure out how to help those managers that might need that help, and help organizations identify potential problem areas in their org structures.
