I’d love to ditch HDMI (even on my television!)

To what avail really? You'll just be changing one cable for another. Also, HDMI 2.1 spec is 48gbps so USB4 wouldn't really be compatible with the latest HDMI version.

  usb-c cable is much slimmer than HDMI (important for my cable management) and the port is much smaller so it's easier to run through the wall. It would be nice to plugin the laptop or computer i have to the TV or projector without lugging around an hdmi port. A comptuer with a handful of usb-c ports would be preferred over one with a few usb-c, and hdmi, a sound port, ...

I'm actually really happy with HDMI. It doesn't change much, has good compatibility and doesn't confuse a video cable for anything else. To me its universality makes it better than display port. My next PC will likely have 2 HDMI ports and that will make me very happy. Lots of USB for other stuff but the speed won't be an issue there - no need for USB 4 data rates because... who needs it?

  Oddly, DisplayPort had no royalties and the later revisions had chaining support. So HDMI won over the PC world but DisplayPort and DVI didn't win over the TV world, possibly due to not having DRM by default, afaik. On a tangent, I did see a ~2004 DVI projection-screen tv at a thrift shop once but I couldn't figure out how to get it to output audio. Then it hit me, it uses regular old RCA cables!

    Chaining is IMHO not very relevant. Connect one monitor to your PC. Then you connect another. You still need a second cable. The question is which device does that second cable plug into? To me its actually more natural for it to plug in the PC than to the first monitor. I can see use cases, but for the average person it doesn't make a lot of sense. OTOH you need a HDMI output per display for up to N displays and that might be a problem for people with 3 monitors. I have opted to just use a single 55" 4K TV instead of multiple monitors, but apparently I'm in the minority. Even with that, I still want a second HDMI output.

An HDMI signal is already permitted through a USB Type-C connector [0]. HDMI, compared to DisplayPort, isn't as good but what really sucks is the copy protection scheme, HDCP; HDCP is responsible for so many of HDMI's problems.
