Apologies. I seriously don't understand that comment though, the patch
didn't touch the management interface at all, in fact it renamed only a
few variables and changed EAPOL frame receiving from using the
management interface to the ethernet framed interface.

I'm not sure we understand each other. The only thing I changed with
this patch and the corresponding kernel patch is that all data frames
including those that are used for management purposes are now routed
through the data interface. Why do you think that is wrong? Reordering
your mail a bit, you also said

which seems to agree with me. You can achieve the effect of letting
*only* EAPOL packets through by setting the 802.1X protection parameter
on the network interface via the private prism ioctl, hostapd doesn't
seem to do that unless explicitly requested though.

The actual technical reason for doing is that subsequent patches totally
remove the management interface and on the monitor interface the EAPOL
frames show up undecrypted.
