I think so.

I suspect the original problem can only be solved by allowing approximate alignment within a specified tolerance.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,788534915

This is easy to understand for `combine_nested`. 

I don't think it makes sense at all for `combine_by_coords`. If you want to `override` coordinate labels values for some dimensions you should have to do it manually. It seems easy to land up in weird edge-cases when you combine that with autoguessing behaviour.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,788534915

These are both default values.

You can avoid this by setting `join=""override""` which will skip the check.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,788534915
