Apologies for the confusion! It's added to the layer datum so that it can be [used in `vector-datasource`](https://github.com/tilezen/vector-datasource/blob/b90a50f532b6381770fd4a8a5ec5e49ee46ebc3b/vectordatasource/transform.py#L3794) to control whether to apply simplification to the geometry at a particular...

I think it's probably a little of both. Here's a table showing how weird it gets if we wanted to extend the current scheme "below zoom 0". Requested Tile |...

Looks like the admin boundary ones are due to this [lovely geometry](https://www.openstreetmap.org/#map=19/18.34305/-66.38158):  The geometry is valid, as there's about a 1cm gap at the base of the "spike", so...

Is it possible to do the translation dynamically, so that Google / Bing trackers aren't embedded and don't load by default, but will load when the user clicks a "translate"...

I think this would be a really useful service to have and, like Nominatim or Taginfo, it could be run independently of the API. All the data can be downloaded...

The queries necessary to generate this output are the same regardless of whether it's done by a sequence of one way/:id/history followed by many node/:id/history calls or a single way/:id/history/full...

The message is coming from Rails' [translations](https://github.com/svenfuchs/rails-i18n/blob/fe07d45ff6db044c24c93570cc4236a63eb5814f/rails/locale/fr.yml#L136), which means that the locale is being set to French. This should be [set by the client request or user account settings](https://github.com/openstreetmap/openstreetmap-website/blob/30757696bd01b54cb95309fa61cf8b15ce066ff9/app/controllers/application_controller.rb#L300-L308).

Ooops, sorry. In that case, it would be best to have a complete (except `Authorisation`) request and response trace so that we can reproduce this.

I think the only API methods which allow updating something guarded with a length validation require a logged-in user. Once we have a request and response trace we'll have somewhere...
