3) Take it out of the address index? I'm not sure if 2) is better or 
not. In the above featured way, there is no error in OSM, hence I would 
say better have the map looking correct, and one address not findable, 
than have the map looking wrong.
The best solution would be a table where all routable lines are defined, 
with their nonroutable counterpart - that would be very complex however.

For my maps, I would prefer 3) - dropping the street from the address index.
