The Raspberry Pi is in dire need of a DP Alt mode USB C port. Those small portable devices would pair nicely with the current wave of Display/XR glasses but they all need Displayport via USB.
And while you can work around that with an adapter it takes away from the simplicity of just plugging in the glasses ( and most of them get quite hot too).
Do recent SoC integrate necessary muxers? Last I checked few years ago, it needed a special multiplexer chip between display out and USB-C port to handle mode switching, and there were lots of engineering challenges and costs involved, almost like using one set of pipes for both coolant water and lubricant oil.
