I think we also need to look at the other reason for mesh wireless (as least my main reason for looking at it right now) is a seemless handoff like 802.11 k, r, v protocols. Apple devices support those, many other devices support it.
I already have 4 APs around my house blanketing the entire house, each AP is hardwired (I don't believe in wireless backhaul when I have a hardwire available). So I easily get close to 200Mbps almost anywhere in the house if not higher on 5ghz band.
But this isn't a solution to me, I want a true handoff, my biggest issue is I work from home and constantly on conference calls using my iPhone on ATT, it has Wifi calling now and since the signal in my basement (where my office is) isn't the best, the wifi calling is great. So Ive noticed each time I move around and the iPhone moves from one AP to another, the audio drops for about 5secs as it reconnects to another AP and the caller doesn't hear me and I don't hear them, so its annoying that I lose that audio for that time while Im talking. So this handoff would fix this.
Secondly the smart devices like Wemo don't play right either in my setup, these folks don't code devices properly, it seems to remember the channel of the SSID vs just looking at the SSID and looking at the strongest RSSI. Remember I have 4 APs, and all have same SSID but had to put them on different channels since I don't really have a true handoff concept here, its your typical hodgepodge of blanketing wireless by taking a few Wifi Routers (higher end ones like Asus AC68) and turning them into APs, so no handoff basically.
So what would've been nice is to see a test on this showing you start off at one AP (the root say) and move around the house and see how well it reacts. True mesh like Eero which claims to have 802.11r support, if you client supports it, should keep connection at all times as you bounce from AP to AP and seemless, so your throughput test should continue with no blips, sure it will drop in speed and pickup in speed, but should pause as it drops and reconnects like say my setup would. Luma claims to have only 802.11k. I had a set of 6 delivered but returned it without trying after I noticed how super basic its UI was and wouldn't even work in my setup (I have too many advanced settings configured like static routes, port fwding, static IP).
