I'm conflicted on this
I understand the 802.11 designations perfectly, they're succint and useful.
I recently attempted to explain the distinction to both my mum and a neighbour - strangely enough, both times while setting up their new wireless routers (broadcasting both 2.4 and 5 GHz SSIDs) and doing the usual rain dance pairing devices.
Despite explaining using VERY high level technophobe language half a dozen times - each time with genuinely easy to understand, increasingly simple analogies - they just couldn't wrap their heads around it. In the kindest possible way, it felt like I'd just tried to explain chess basics to a toddler.
To most non-technical people, Wi-Fi is just a wibbly thing which usually runs well, sometimes runs slow, but is A Thing Which Basically Works. If it's easier to explain to my mum why her router now advertises a Wi-Fi 5 and a Wi-Fi 6 hotspot, while her old tablet can only see the v5 wibble, that's fine, I get to the pub quicker.
If I can toggle marketingspeak for descriptive labels (a/b/g/n/ac/ax) on my devices, I'm OK with this. I'd rather devices be able to display estimated mbit/sec throughput - or even just dBM - with a simple toggle, instead of arse about with third-party apps.
