Thanks, that's exactly the right issue on NM side.
My thread opener here was looking for how to get wpa_supplicant to automatically do more.
Looks like as we're heading into 2.11, such still won't be the available.
"hostapd doesn't have DBus" - unlucky! Probably an even bigger project than getting wpa_supplicant upgraded?
So that might leave us with NetworkManager as the fastest way forward:
* could NM expose more "custom configuration" options? I doesn't have to bear the full autoconfiguration burdain, and risk getting things wrong.
* can wpa_supplicant run a DBus configuration + custom enhancements in /etc/wpa_supplicant/*.conf?
