As long as the current guard model is in place then the relay could
probably tell if its a client vs bridge by the frequency of visit. I'm
assuming that a client visits one of its guard more often on average
then a random bridge would connect to that guard. There is probably
something in the code that tells the node which spot they are in.

The network would be slightly less secure because the chances of
having the first and last node would be improved, making correlation
attacks easier. It would how ever not be a third easier though,
because of Guards and exits wouldn't be used (much) as a middle node.
