...a city with 3 besiegers would "score" -1 point per tile and pennant!
Correct, no stacking effect on Cathedrals or Besiegers. That would be crazy powerful. Imagine though, that you are in a large city now with 4 besiegers on it. Thanks to the competition. The tables would turn - you would be trying to block it so it can't be finished and opponents would be trying to finish it for you. You might even be trying to glom onto someone's city to suck them in with you. Yet, finishing it would still score more than end-game scoring. That would be a weird twist.
