Ah yes, but technically you can always send whatever you want. The
question is whether it will (a) reach the given destination,
(b) reach a pre-determined other destination, or (c) be
dropped. So, if you send a ping or a tunnel packet to another host
on the same link, using a link-local address, what will happen?
Are you "connected" if all your packets get treatment (c)? No.
Are you "connected" if all your packets get treatment (b)? Hmm...

Or perhaps the point is moot. IPv6 with webpage login screens!
Sigh...
