Well, they interact very deeply, for example the # of virtual interfaces
is often severely limited, and they often have to be using a single
channel, etc. It thus doesn't really make sense to try to separate them.

Also, if you really want to use it reliably, you should use a single
hostapd or wpa_supplicant process controlling all virtual interfaces,
which clearly isn't possible in multiple network namespaces.
