I'm not even sure why they need wifi 6. According to the specs page, the chipset supports wifi 5 2x2 80 mhz, which translates to a theoretical speed of 866.7 Mb/s. Even if we halve or third the speed for "real life" speeds, that's plenty enough for whatever can be done on a lowend phone. Even if you're downloading netflix videos (to watch later), you'll probably be bottlenecked by the slow eMMC storage.
Meanwhile 5G is significantly faster than LTE, probably due to better spectral efficiency as well as being less congested (less 5G devices around). In congested areas I'd only get 10-20Mb/s on LTE but 200+ Mb/s on 5G. That's far more useful than getting 866.7Mb/s vs 1021 Mb/s over wifi.
