I don't know. My last 2 PC laptops have been incredibly thin yet still don't have the spec-suck that you see with apple offerings. Current Dell XPS 13 Dev Edition and an HP Spectre x360 both managed to be light, while still having great processors, plenty of Ram, fast nvme drives, good battery life and 4K displays with touchscreens. Both managed to have more than 1 port. Being less thin certainly gives you more room for "stuff" but I don't think lack of it is what's causing mac to fall behind.
