Roon clamps the samples when they exceed the bounds, so there is no concern about damage. The clipping indicator is informing you that a sample value was limited, not warning that a dangerous sample got through.
All clipping introduces distortion. Soft-clipping creates distortion that is less offensive to the ear, but it is still undesirable. Soft clippers make more sense in systems where you can’t anticipate signal levels in advance. That is not the case in playback software where a small, fixed amount of headroom suffices to totally remove the problem.
