Any of the flavor maintainers would be better suited to answer this specifically, of course, but are there any feature differences (strictly speaking) between flavors that aren’t functions of the desktop environments’ differences themselves? (Other than with Edubuntu and Studio, which perhaps are the main areas of interest for this question?)
Just thinking of what areas would be of unique value to capture for Ubuntu flavors themselves, as opposed to the wide number of desktop environment comparisons that exist out there?
