Yes, AutoConnect will still remove outgoing connections that it thinks
are redundant. So even if the initial ConnectTo's will cause nodes to
connect to the yellow ones, after a while they can remove those.

If you make the yellow nodes ConnectTo all other nodes, and not have
AutoConnect = yes, and the other nodes just have AutoConnect = yes but
no ConnectTo's, then you will get the desired graph.

I should've elaborated here.
