I looked up the history again, and it's clear that the healthcare tags which duplicated common amenity tags were never popular until they were added to the iD presets in 2017:
https://taghistory.raifer.tech - compare "healthcare=pharmacy" and "amenity=pharmacy" - the Healthcare proposal was approved in November 2010 but usage is not visible till 2017 Request to add more healthcare presets: https://github.com/openstreetmap/iD/issues/3589 PR which added them, duplicating the amenity=pharmacy tag with healthcare=pharmacy: https://github.com/openstreetmap/iD/pull/4329 Note comments against deprecating amenity=* tags in this issue and PR: "I don't agree with deprecating tags like amenity=hospital or amenity=doctors, which are in widespread use. But we could probably add the new healthcare tags alongside the old ones." "Yes, I was just talking about addig this one, not deleting the others." https://github.com/openstreetmap/iD/issues/3589#issuecomment-260979736 There was no intention to replace amenity=*, and mostly the PR added new tags. Almost all of the usage has come since this change, but note that amenity=pharmacy is still significantly more common than all uses of the healthcare=* key, and it is increasing in spite of the iD editor making an odd choice of validation rules. - Joseph Eisenberg On 1/29/20, Paul Allen <pla16...@gmail.com> wrote: > On Wed, 29 Jan 2020 at 12:51, Lionel Giard <lionel.gi...@gmail.com> wrote: > > Is there something that i am missing here ? ^_^ >> > > Rendering.
