Currently no way to create a Coordinates object without indexes for 1D variables

4

### What happened? The workaround described in https://github.com/pydata/xarray/pull/8107#discussion_r1311214263 does not seem to work on `main`, meaning that I think there is currently no way to create an `xr.Coordinates` object without...

### What is your issue? In https://github.com/fsspec/kerchunk/issues/377 the idea came up of using the xarray API to concatenate arrays which represent parts of a zarr store - i.e. using xarray...

### What happened? Vectorized indexing can fail for array types that strictly follow the array API standard. ### What did you expect to happen? Vectorized indexing to all work. ###...

I just learned what [`collections.ChainMap`](https://docs.python.org/3/library/collections.html#collections.ChainMap) does, and one of the [examples](https://realpython.com/python-chainmap/#managing-default-argument-values) of its use is to manage overriding default keyword arguments, e.g. ```python from collections import ChainMap class CRMUser(User): def...

[BUG] Time coordinate being dropped by apply_as_grid_ufunc
