Not sure this is really "new". Technically it is a new wifi standard but there has been equipment sold for long range wireless connections on the 900mhz band for many years. Many WISP ISP use a variation of LTE running on the public 900mhz frequencies. It is unlikely commonly used wifi devices...like phones..will add 900mhz wifi support so it is still a very niche use case.
 
Part of what makes this test impressive isn't just the sheer range at which a working Wi-Fi signal could be accomplished; it was its ability to work at that range despite all the real-world wireless interference of the surrounding urban area.
...but I'll bet not anyone else using specifically 802.11ah! If this were already deployed at scale, I sure doubt they'd have gotten it to work nearly that well.

Of course, I say that without knowing anything specifically about 802.11ah, but I just think the collision-avoidance techniques wifi uses probably can't scale well to a high-density deployment environment.

This could still be very useful for things like agriculture, where more machinery is becoming wifi-enabled and the amount of interference is going to be low by definition.

Not 802.11ah but there are many things like the automatic wireless meter readers used on water and power meters. Many of these run in the 900mhz radio band. That could be a massive amount of traffic in areas with apartments that have all separate meters. I know the outdoor sensors on a old weather station thing I had all ran in 900mhz. Radio signal is radio signal it will all interfere.
 
Excellent, 900 MHz is the frequency that industrial microwave ovens operate on. https://cooking.stackexchange.com/questions/115059/microwave-oven-operating-frequencies

So I can heat my lunch.
Luckily you need not wait for 900 MHz Wifi to heat your lunch. Regular wifi (and Bluetooth, and cordless phones if anyone still has one) operate at 2.4 GHz (in addition to 5/6 GHz for newer wifi standards), the same as home microwave ovens.

Of course, finding a signal in either band powerful enough to heat anything fast enough to notice may be a little tricky...

Actually most any radio frequency can be used: https://en.wikipedia.org/wiki/Dielectric_heating#Radio-frequency_heating

It was more of a joke/suggestion that long range Wi-Fi would use more power (though it gets some of its range from the lower frequency) than the GHz+ bands; thus polluting the band at a greater distance, making it harder to find a mostly clear channel.
