So on my current running iwm setup without changing anything else I did
the devtl detach, set driver dance which failed as follows:

ifconfig: interface wlan0 does not exist

My next action could be to define both wlans_ entries in rc.conf and set
the devmatch_blocklist to if_iwm and reboot the laptop (without
rebuilding world and/or kernel) ?
