Those at least have engineering & financial constraints driving them. Like you can't mandate everything USB-C can provide 100W of power delivery, it's a combination of just not possible and just not economical (eg, your phone would never be a USB PD source as a result, which is a handy feature to have today for charging headphones & the like) Also, those specs all have a degree of interoperability, which is a pretty significant difference. Like many thunderbolt 3 docks can actually also just run when connected to usb-c w/ dp-alt mode, although they lose out on the thunderbolt extras of course. Something that seems to be missing here.
