I can understand getting your hands back on the TLs on the approach as hopefully you’re going to have them there for the landing but in the climb out they will be at a fixed setting and in most Boeings will have gone into HOLD for a bit, so why bother? At best nothing happens and there is the distinct possibility of unconsciously moving them to a power setting you didn’t want, especially in turbulence.
I may be turning into a curmudgeon but I am somewhat triggered by people who hang onto the controls and thrust levers well away from the ground when both the autopilot and autothrottle are engaged. If you don’t like what the automatics are doing, disengage them and fly manually - don’t apply pressure trying to force the automation into doing what you want as this doesn’t work!
