Allow product variation (delta) sorting by SKU or label

Your project might have different sorting requirements than any other site would need... I don't think we can build something generic here that suits everyone...
You're free to use a contrib module like https://www.drupal.org/project/draggableviews → and implement your own sorting logic... I don't believe this logic belongs to Commerce core.

Thanks for the rapid feedback @jsacksick!

Yeah of course you can discuss that. I think the three values might match 95% of all commerce projects, but I'm unsure who of these need sorting for variations at all. If one day more people report their need here, we can reopen this.

Note: The variations list within products is not a view. So this can't be solved using a views-based module. But it could surely be solved in commerce contrib.

Thanks! :)

This can be replaced by a view in your project is what I'm saying.. This isn't done in Commerce to not introduce another contrib dependency such as Draggable views.
