Agreed. Extending things like the LAN connection is usually actually a downside in most "PC in another room" cases and USB/display are already very easy/cheap to extend great distances. Being it's a PC in another room you probably don't want to plug in actual PCIe devices locally (GPUs, high performance disk, whatever) since it defeats the point of having the PC in the other room. The only real upside of Thunderbolt is it had the potential to bring things down to a single cable, assuming that single cable had enough bandwidth for your needs (e.g. a single HDMI 2.1 cable can deliver more bandwidth than an entire Thunderbolt 4 cable).
