> If it's part of every modem/gateway router

If it's a part of every modem/gateway router, why would you bother routing it through a bunch of mesh hops just to eventually get out instead of just routing it through the far more reliable wired networking available at every modem/gateway router?

Those regular WiFi networks only have tons of available bandwidth because they're not trying to repeat a bunch of wireless traffic. Even the current mesh WiFi networks only really work when you're using frequencies that aren't trying to compete with neighbors. Start getting actual density and it'll all fall apart.

Also your idea of "standard QoS can still apply" isn't exactly true. That QoS is only going to work if people play along with it. In the end its a shared medium. Get some clients to not play along with your configurations, you'll start getting collisions regardless of what you configure your QoS settings.
