The draft defines three different ways to advertise gate over the
mesh, leaving the implementers choice of which one(s) to implement.
We chose the one that was best suited for the most common usage
scenario.  I would not call that a limited implementation but rather
"an efficient implementation of a bloated spec" :)

Yes it does.  Gate announcements should only go out if a node has some
other interface connected to an external network.  If the external
interface goes down, one would want to stop gate announcements
immediately without bringing down the mesh interface.
