I'm a little doubtful about this. Currently, mac80211 will keep the
channel if you set it on say wlan0, your monitor iface gets the same
channel. Then if you remove wlan0, you still have the same channel, but
it seems here this is different now? I'm not sure it matters much, but
it's worth thinking about? Or am I totally misunderstanding this now?

Right. It's not the exact same behaviour. It only guarantees a channel is always set in monitor mode. We could maybe set the last monitor-mode-channel seen when starting up monitor-mode again. Would that be okay?
