What happened?

Currently we don't overwrite indexes when region="auto" https://github.com/pydata/xarray/blob/e6ccedb56ed4bc8d0b7c1f16ab325795330fb19a/xarray/backends/api.py#L1769-L1770

I propose we do this for all region writes and completely disallow modifying indexes with a region write.

This would match the map_blocks model, where all indexes are specified in the template and no changes by the mapped function are allowed.
