I think the versatility people talk about mostly comes from the player and mouthpiece, but that kind of reveals the elephant in the room. At least for me the issue with the Truetone has always been mouthpiece matching.
And if you particular definition of a sound for modern music involves certain types of mouthpiece, you will be fine but possibly out of luck in regard to getting the best intonation.
But I would say that if you do totally have to rely on a certain mouthpiece for a certain sound, it could be that it's the lack of versatility due to your embouchure that is restricting you rather than the mouthpiece per se.
In other words some people may be able to get more versatility with a mouthpiece that's a better match (intonationally) for a True Tone, while others might struggle, and so think they need a more "modern" mouthpiece for that sound they are after. And then find they suffer some consequences in pitch.
