I bet companies will release WiFi 8 products even when it's still a draft, just as they did with WiFI 7.
I upgraded my home setup to WiFi 7 a few weeks ago, and after being a WiFi hater for so long, was actually surprised at how much better it was over my previous experiences with WiFi. With MLO clients get 2-3ms latency with 2.5Gbit links, I'm all for WiFi 8 trying to reduce the latency further, I don't need more speed.
With MAP 2.4GHz can serve as long range network that can be filled with High-Rate 5GHz / 6GHz cells. And all of them can be utilized in parallel.
802.11be (Wifi-7) still lacks this.

So they're explicitly look at more than just adding more bits per second.
