Moreover, you *shouldn't* define the same real-world object multiple
times. There is not two different real-world things - "HOT Schools"
and "Schools" - there are only schools, sometimes with additional
information provided relevant to HOT purposes. Therefore there should
only be one feature in the presets tagged amenity=school - you should
not create an additional "HOT School" feature, you should edit the
existing "school" feature to have additional information.

Same goes for highways - I'm still concerned that there's going to be
huge conflicts between your (shortened) "HOT Roads" list and the
normal OSM roads. Avoid duplication and especially data loss.

I think we might need to update P2 to reject duplicated features, but
this might be tricky to get right.
