I might believe you that USB (or Thunderbolt) is imperfect both to transmit video to my display and to charge my phone, but the thing is, it does it well enough, and even if using some special charger will give me twice the speed, I honestly don't care, the life quality that simplicity of using 1 cable gives me far outweighs the hypothetical efficiency advantage of 10 specialized cables. The only case when I can consider a dedicated output on a consumer-grade hardware is when the signal is fundamentally analog. Otherwise, why should I even care, if both the bandwidth and latency are mostly fine and voltage is ok to power up my device?
