I mean, the Playstation 5's hardware is done and dusted at this point.
Thunderbolt would've been sick. For many other reasons than PCIe expansion, as 40Gbps might not cut it as you said.
I guess I and others don't see sliding off a panel and putting in 1 screw as a big deal, similar to the PS4 method of sliding off the top left plastic cover and undoing one screw. I like MS's method, only issue is that it's a more expensive option than buying third party hardware.
