Let me highlight a few mixins <https://github.com/pydata/xarray/blob/6a20f917041abf53bcb35e210d59f5b331211012/xarray/core/utils.py#L381-L425> that I wrote for xarray that might be more broadly useful. The challenge here is that there are quite a few different meanings to "ndarray-like", so mixins really need to be mix-and-match-able. But at least defining a base list of methods to implement/override would be useful.

Slightly off topic, but as someone who has just spent a fair amount of time implementing various
subclasses of nd-array, I am interested (and a little concerned), that the consensus is not to use
them. Is there anything available which explains why this is the case and what the alternatives
