One thing to keep in mind: Pilots can always use stealth mode on their own. If it bugs you that someone may follow you, then turn on stealth. The issue is mandating it for all.

If you are in Stealth, and your competitors are not, you are strongly disadvantaged from my experience. I stubbornly tried it. If the Flarmleechtool is in use, one can not afford not to be using it.
And- dirty little secret- pilots are covering their antennas when they think they are in the lead so as to not give away information. One well known world champion has been doing this, according to those I believe are in the know. "Whats the aluminum foil hat for?"
