It does sometimes take its sweet time about it, but most of the time, it
eventually (between instantaneously and about 30 seconds or so) does
attempt to connect.

You're right, it's not perfect.  But AFAICT it doesn't make a habit of
randomly connecting to unknown networks.  That's the safer fallback.

One thing I've learned following the NM mailing list: wireless is not
simple.

BTW, the answer to the OP's question is to include NM_CONTROLLED=yes
in /etc/sysconfig/network-scripts/ifcfg-<device> for interfaces NM
should control and set it to 'no' for interfaces that should not be
used.  At least, that's how it is in F8.
