StreetComplete does not use sidewalk(:*)=none since streetcomplete/StreetComplete#3194

This repo hasn't been maintained since a long time. You'll notice that this repo is also not part of the repos in https://github.com/streetcomplete/ space for that reason. Even if this PR is merged, the rest of the JSON is still hopelessly outdated.

@peternewman has been working on an automatically-generated replacement streetcomplete/StreetComplete#2754 , not sure what the status is. It seems to be stuck? Maybe you would like to help.

I would love to help but I have never written in Kotlin or Java.

See #21 this repo isn't used anymore! If @goldfndr does anything to this repo then it just needs archiving as per #20 and a comment adding to it pointing to the script which generates the current live datasource!
