I got a thunderbolt 4 dock from Razer[0] that has all the bits and bobs (and it looks really nice). Almost bankrupted me, but as the GP says, this is just the reality at this point.
The port arrangement on the front/back of that looks identical to the Kensington and Sonnet docks mentioned upthread, so I'd suspect that Razer are another vendor of a skinned reference design. (Though they're on the cheaper end of the spectrum so far, unless someone turns up the Aliexpress version.)
