That would be fine if this were an employee manual, where people who don't follow arbitrary rules can be disciplined or fired, but the purpose of this document is to provide guidance to a group of volunteers who are unsupervised and pursuing their own personal motivations. If you just tell them "don't map X" without explaining why, they will ignore if it they feel like it. At a minimum, this document needs some explanation of what is the difference between a landmark and a POI, and why it matters for mapping.
There is another document being prepared that will explain the difference between Landmarks & POI and provide more detailed mapping instructions. Those are just the type by type guidelines. That is explained by this part of that topic
the Waze Champs are currently working with the Waze Staff to sort out some misconceptions about landmarks (snapping to roads, suppression of various reports, etc) and will also be creating a page that better addresses the Theory of Operation behind Landmarks shortly.

Why is the "historical importance" of a cemetery of any value in deciding whether it is useful to drivers seeking to orient themselves on the road network? Why are parks or schools, which may be located far off a road, more useful for navigation than a store or office building? A McDonald's at a major intersection may be a more useful landmark than a church that is at the end of a long dead-end street and not visible from any other road. Again, what's the reason for these distinctions?
Well, there is a long standing guideline that we "do not map individual businesses", so that takes care of McDonalds, etc. The thing you need to remember is that Waze isn't going to say "Drive to McDonalds and take a left", it will tell you to "turn left on Main St", it does not matter if McDonalds happens to be at that intersection.
As for the Church, it typically would not get mapped as most churches are not considered "Major" - think more along the lines of the Vatican, Kaaba, & Western Wall.

The Waze Champs, Country Manager & Area Managers actually do supervise the editors, make sure people are following the guidelines, and communicate with the editors. You should also be aware that editors that do not follow the guidelines and refuse to communicate with the Champs can and have had their editing privileges limited and/or revoked.
