I think the OP raised a question about the behavior of the TC assist, not about how/when/if to use it.
The assists should be appropriate to the context of the game/sim, and not be overpowered or unrealistic in application.
TC should limit wheelspin, not adjust the suspension. For the top drivers it should be slightly slower as would be expected all else equal.
If people choose to use it and it helps them enjoy so be it. Personaly I’d like to compare myself to those using similar setups so filters would be my pref
