Playing USB-Cs advocate, a world where every specialist connector on a laptop would double as another USB to hook up random gadgetry when not in use as the primary role would be awesome. For example I never use that HDMI or the ethernet port. They exist because situations where the matching plugs are part of infrastructure you don't control, but I might prefer a world where those plugs need to be labeled because all the ports are the same to double as lowly gadget hosts. What's bad is the usual implemention where you have one "holy grail" port that's effectively a proprietary docking station connector (because no other docking station has the exact same subset of "concurrent beyond-USB stuff") that might downgrade to some single usecase protocols beyond serving as a lowly plain USB. But where you have a serious lack of other "USB and/or X" beyond The One. This quickly gets ugly when you want to connect display and power separately. You absolutely need another port that's also capable of delivering power (or the reverse, a second display-capable USB so that power can be fed in isolation via the docking-capable port), but this is unfortunately rare, instead you get special ports that are completely useless while doing the docking station thing.
