In addition, IEEE 802.1X requires that EAPOL packets are passed through
unencrypted, which requires host-based encryption with current firmware

I have updated hostapd code to latest 802.1aa draft. However, couple of
changes are commented out since they seem to break key distribution. As
far as I know, it would be fair to say that 802.1X code in hostapd is
mostly standard compliant. As far as 802.1X use with 802.11 is
concerned, yes, it is currently, for many parts, de facto standard.
Anyway, some parts are specified in non-normative Appendix of 802.1X
