Given that the expansion ports are just USB C ports, the real innovation (one of them) is making an integrated dongles. The only issue I see is that the adapters are a big too large but also a bit too small; the adapters are large enough that there are only 4 but also small enough that making a 2x USB A adapter would be quite challenging.

I think the idea could be expanded upon. Dongles that extend beyond the chassis such that they protrude a bit but make a flush contact with the laptop chassis. This would let you basically turn a typical USB dock into a permanent extension. Perhaps instead of having an two expansion ports on each side, each side of the computer including the front & back would have one larger port. I don't think having two USB C ports does anything to increase overall bandwidth available since it's probably all shared anyway.

Also once Thunderbolt 4 and USB 4 are available it should make creating standardized expansion adapters a lot easier since you won't have to worry about an adapter needing Thunderbolt on an AMD system.
