Ooo I had a thought for this that might be good. People have talked about how they want infiltrators to be invisible again.
What if, bear with me, the fact that you are an infiltrator is what's invisible. The subclass doesn't show up on your normal profile or any other list. It can be hinted at under "listen to rumors" and similar investigative means, but the only way to confirm it is if you are caught in the act. With this new start uprisings feature there can be a risk that police will raid your meeting place and catch you paying off the mercenaries. Other infiltrator actions already carry the risk of being caught and identified.
This would better justify the need for high honor and prestige, you need it because people would never suspect a rich, prestigious and trusted noble of being involved in such sinister plots.
Now that sounds like a very exciting new feature.
