The physical layers of everything are converging. The breakthrough we need is on the logical layer, with peers describing their capabilities and working out a sensible, predictable suite of resulting functions. Right now there are _zero_ conventions for what the DP Aux stream should do, so random member of the public has no expectations. HDMI for the most part does what normal people expect. USB has maybe a few too many possible outcomes ... for example yesterday I discovered that my Pixel phone was charging my MacBook, instead of the other way around. Unfortunately working out a set of norms and expectations that are useful to users is harder than just making bits go over wires.
