The idea of a relation that would link a peak to its key col and line parent would do nicely for that. All of the peaks around a caldera, except for the highest, are going to be subsidiary peaks, directly or indirectly, of the true summit. I live in country with long ridges, and almost anything with enough isolation and a little bit of prominence winds up being a named summit. Otherwise, you would get into the situation where you call everything a subsidiary peak, and that doesn't feel quite right on a ridge like this. And there are clusters like this one: One of those has over 600 m of prominence. The one next to it has about 60 m of prominence. Which is which? The elevations of the summits differ by less than 10 m. (The locals count them as distinct peaks.) I'm fine with listing prominence, so that renderers can decide for themselves what's 'significant', but I think that to distinguish 'mountain' from 'hill' we need to leave the final decision to the locals.
