Most Wikipedia guidelines are not set in stone or meant to be blindly followed. They need to be applied with common sense, and often, flexibility. The WikiProject suggestions on how to write about settlements do not have any sort of official status, and definitely shouldn't be forced on editors of individual pages. Having said that, I think the differences of opinion here are matters of interpreting the basic ideas behind the guidelines, not the result of ignoring them. While I still maintain it is quite reasonable to mention schools in this article, I also agree that it is sensible to focus on writing about education at a borough level, but in my experience, Kb, people work on the articles they want to work on, and trying to direct peoples productivity to particular ends is largely unproductive.
