There are a few options here:
- Just change how `roll` works (as a breaking change) in xarray v0.11, with the argument that the current behavior is broken/useless. This is easiest if we aren't concerned about backwards compatibility, but unfortunately I'm pretty sure at least some people rely on this, e.g., based [this StackOverflow post](https://gis.stackexchange.com/questions/205871/xarray-slicing-across-the-antimeridian).
- Deprecate the current behavior, e.g., by inserting a new argument `coords=None` which by default shifts coordinates (equivalent to `coords=True`) and raises a warning. In a future version of xarray, switch the default to `coords=False`.
- Implement the desired behavior in a new function (`roll_axis`?) and deprecate `roll`. This is the preferred option for mature projects like NumPy.
I am loathe to loose the name `roll` so this second option is probably the best choice. Any interest in putting together a pull request?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,293345254

I agree that the circular coordinate is used in many physics fields (actually I'm not from geoscience and I also sometimes use the circular coordinate), but one confusing sene I can think of is when using it in radian, (0, 0.5 pi, pi ...).
Manual overwite would be more explicit
Another option could be to add a circular cooredinate class after #1603 is implemented?
