Right. In my list above I tried to have just the ones that seem 
to each be 100% supersets of previous generations replacing the
earlier ones, which isn't true for RTL81xxDU as RTL81xxEU
reverts to single PHY.

My guess is that these devices have largely been replaced by
802.11ac devices on the market, and whoever has one of the old ones
probably bought it because of the 5GHz support, so adding 2.4GHz-only
support for it may not help all that much either.
