WIFI 7 was supposed to make 6GHz usable - due to stronger signal and more bands. But it seems likely that it wont materalise outside US.
We are getting shafted again, there is no point in reading US reviews of these routers, they will perform very differently here(to be frank, its similar with wifi 6 - EU speeds on it are nowhere near speeds you can have in the US - especially with things like dedicated backhaul on UNII-4)
Great to know the certifications and standards are useless.
I guess ATM I can hang tight. My PC 2 floors above my main router and wired to a Zenwifi AX mesh node and gets 800mbps of my gigabit. Don't suppose anything exists to get that to full gigabit, but even then still just an incremental improvement if so. WiFi clients on the 2nd slower 5ghz band aren't overly speedy, though, at 500-650mbps.
