A groupby like interface is much cleaner than adding more orthogonal code paths to .mean and the like.

Like most new features for pandas (or xarray, for that matter), there isn't anyone who has committed to working on it -- it will depend on the interest of a contributor.

You already have most of what you need -- it would just be a matter of dropping `mean` from the list of injected methods.

https://github.com/pydata/xarray/issues/770 might help with some of the redundant code (if/when we get around to it).

Otherwise, I would be inclined to simply add `weights=None` to `mean`. That would require a bit of refactoring but shouldn't be too bad.

I guess it's nice that this mirrors NumPy.
