Hmm, this seems like a grey area... I think selecting along 1D non-dimension coords is probably way more common than along 2D coords, but I'm biased.

> changing the number of dimensions doesn't change functionality

BTW I can immediately think of at least one other place where this rule is broken (#3774) - where going from 0D coords to 1D coords of length 1 changes whether `combine_by_coords` will accept them.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,592312709

Sorry, could you explain what you mean here? How would this PR violate that?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,592312709
