I've added this to the corresponding ticket over at the oshdb repository: https://github.com/GIScience/oshdb/issues/311

I think we can agree that the `is_valid` filter would work on the principles/definitions of the simple feature standard. There is one additional aspect we have consider here: There is...

> So what is the difference between the response of /fullHistory vs. the response here of /contributions? To me the main difference is that `/elementsFullHistory/` not only returns the changes...

with country/region/city boundaries there are some quirks to consider: * which definition of boundaries should we use? _think of disputed areas, but also the difference between land mass vs. the...

Since polygons' vertices are always assumed...

good catch, @SlowMo24! I would indeed consider this as a bug (in the OSHDB), and have created https://github.com/GIScience/oshdb/issues/433 for this.
