In most situations, that's the only AP that matters. If the situation changes 
such that you lost the connection in the first place, it's highly unlikely 
that you'll be able to reconnect to it quickly, fresh scan info or not.

I think you need to acknowledge that single AP deployments are a very common 
occurrence. Yes, there are offices and hotels and other large buildings that 
deploy multiple APs throughout a campus, where roaming is an issue. But you're 
trying to force NM to act as a one-size-fits-all solution and that frankly 
isn't reality.
