Sort of.
Those with the Part 107 Remote Pilot Certificate can still fly recreationally without a TRUST, as long as they are flying under the Part 107 regulations. In that case, they don't need a TRUST completion cert on them.
But if they fly outside those rules, they do need one. The examples are if you want to fly an aircraft over 55 pounds, or if you want to fly at night under a CBO that doesn't require 3SM strobes. If that case, you need to have your TRUST.
Also, if you have any UAS registered as a recreational flyer, you need to have taken TRUST in order to fly them outside. That includes ALL drones under .55lbs. For instance if I'm going to fly my little EMAX TinyHawk 2 drones outside (assuming there is zero wind), I have to have the TRUST. And I do fly those little guys at my local playground when the kiddos aren't around.
So in those cases, I need the TRUST. All other times, I can fly under 107, even if I deem the flight a recreational one.
I hope that helps clarify some of the TRUST concerns.
