> I'm assuming the main issue here is to have combine_by_coords put a set of unnamed DataArrays into a single group and paste them together.

Yes - which involves making the assumption that these different unnamed DataArrays are actually the same physical variable, and so can be meaningfully combined into a group.

I think that if we go with the [scheme suggested](https://github.com/pydata/xarray/issues/3248#issuecomment-526263925) by @dcherian for handling this issue then it answers the [question I posed in #3312](https://github.com/pydata/xarray/pull/3312#issuecomment-652363949) - the answer being that we care more about `combine_by_coords` happily accepting two unnamed DataArrays than we do about it being consistent with `merge` by throwing an error. If we're happy with that then I think it shouldn't be too difficult to finish off the PR in #3312?

(I think that [this bug mentioned in #3312 is separate](https://github.com/pydata/xarray/pull/3312#issuecomment-568789721), and possibly deserves its own small issue.)","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,484270833
