And Thunderbolt. I’d love to slap a midrange external GPU on for when I want to play on my 1440p monitor.

Thunderbolt is too expensive for the Steamdeck. USB 4 should do the same but cheaper.

Oh cool, whatever works and is affordable
But USB4 is Thunderbolt?
With USB4 the PCIe tunneling is optional; with TB it is mandatory.
Ehm, the specification is clear that all external ports should expose PCIe tunneling? Or is there something that changed?
I don't know what Microsoft based their claim about it (maybe their own requirements in Windows HCP?)
From the spec:
2.1.1.5 USB4 Host
Host contains:
* A Host Router.
* A USB 2.0 Host.
* An Enhanced SuperSpeed Host.
* A DisplayPort Source.
Host can also optionally contain a PCIe controller or PCIe switch.
A USB4 Host supports 20G USB4 operation (Gen 2). It optionally supports 40G USB4 operation (Gen 3) and 80G USB4 operation (Gen 4).
Hmm, you're right - it's Windows HCP. I found a random statement when they mandate tunneling support to "Maximize compatibility across ecosystem".
Well that does seem short-sighted. :(
