I do not know about the the others, but rtl8712 is still in use according to the 
flow of questions I see on a GitHub repo that I maintain.

There has been some recent effort to convert rtl8192e to use cfg/nl/mac80211. 
That one is problematic as it has the same PCI_ID as RTL8192SE, but the drivers 
differ. Note the special code in the probe routine of 
drivers/net/wireless/realtek/rtlwifi/rtl8192se to detect if the wrong one has 
triggered the routine. That code should also be in the probe routine for 
RTL8192E with the test negated. I have both devices, but it has been a long time 
since I actually used either of them. I also have an rtl8712 device, thus I 
should be available for testing.
