See w3c/csswg-drafts#13238 for an example of where this would be useful. Some changes were made that added a new level of substeps to an algorithm, but the author indented them by 2 spaces instead of 4. In the source, this looks fine, but Bikeshed treats these indented steps as being at the same level as their parent step. I don't know if outputting a warning for this is viable, but I thought I should raise it here.
