You're misunderstanding what is being proposed. It's not saying 6GHz shouldn't be used for WiFi. It's saying that 6-6.4GHz (approx) is reserved for WiFi and 6.

You're misunderstanding what is being proposed. It's not saying 6GHz shouldn't be used for WiFi. It's saying that 6-6.4GHz (approx) is reserved for WiFi and 6.4-7GHz should be used for cellular networks. My point isn't that we shouldn't have no WiFi on 6GHz, but 1GHz extra for WiFi is limited utility compared to cellular networks. You can still fit an entire 320MHz channel width in the lower 6GHz and if it doesn't overlap like you say why bother with 3x that?
