It should be the user's responsibility (or the image recipe's) to choose the
wifi daemon, and it should be possible to uninstall one and install the other
from a package feed, or even to install both at the same time and use one for
wlan0 and the other for wlan1.

Debian enables support for both daemons in connman and has the following
package metadata:

Recommends: wpasupplicant | iwd

I don't know whether there's a way to generate that line in OE. If not, you
could try to fake it by adding RPROVIDES_${PN} = "iwd-or-wpasupplicant" or
something similar to both daemon's recipes and recommending that in recipes
supporting both daemons.

Best regards,
