It would be nice if we could form a sensible
compromise solution like
folding most of the non-notable ones into district or county or town
articles. I'm not sure this is possible given that most sensible
people probably want to stay out of the school debate.
And also because not everyone is going to agree that this is "sensible".
I've merged plenty of articles in my time, but the recent trend towards
pasting together a whole bunch of small articles on narrowly-focused
topics into one gigantic mega-article with a section on each, leaving a
redirect behind, seems like a backwards way to go about it. All the same
material is still there, it's just harder to find the specific thing
you're looking for.
