Perhaps; I tend to think it's a matter of opinion on that one.  I think
what you really want here is for that property to just not exist when
there aren't any wifi devices, but it's not really great behavior to
make properties disappear either.

One could argue that even though there isn't wireless hardware, no
killswitches (which are often independent of the actual wifi hardware)
are set, and thus there isn't anything blocking wireless.

Also, (ab)using that property as a shortcut for whether a wifi device is
present or not is also somewhat questionable :)

Cheers,
Dan
