Seems so. If you think about it, having smartphones, smaller tablets (<= 7") running the same OS as 10/13" tablets didn't make sense in first place, because they're just used differently. This also reflects in UI design, it makes more sense to group a 10" tablet into a small laptop category, instead of grouping them with 5 ~ 7" phones or small tablets half the width. From a holistic perspective, regarding UI frameworks and the developer experience in general, grouping by screen real estate vs. device category could make the entire organization of things much simpler, improving the developer experience by a lot. Apple might do the same, turning their iPads into their new non pro laptop line down the road. They already ditched the "mini" versions of their tablets a while ago, and their UI framework switched from device category adaptability to adaptability based on screen real estate. (e.g. a phone app could just be a sidebar, and a tablet app the main content area on a 16:10 screen).
