New, good - Retrospective, bad
I'm all for a more easily-undersood system that helps us spot this year's model from last.
But retrospective re-designation is stupid: if I check my current device spec sheet and it is some 802.blah number, how can I relate that to "Wfi 5 or 6?" or, "is "WiFi 4 too risky to keep any more?" type information?
