If you were to add a weighted shiftknob that was so substantial (something close to the weight of your hand and arm) over time you would start to have a force that would be constant pushing the shift forks into the synchros. Exactly like why you shouldnt rest your hand on your shifter while you drive, or keep your clutch pressed in when you're at a stop light. You're doing extremely small amounts of wear, but for very very long periods of time.
But that would be a ridiculously heavy shift knob, something in the range of 10lbs. Whereas a heavy weight shift knob is around 1-1.25lbs. So the forces are significantly lower than the situation where you're resting your hand on the shift knob constantly while driving.
So in short, any additional wear would be negligible from weight alone. And as far as increased wear from shifting into gear very aggressively? You can expect that to be the same. it's a very short momentary force, and pretty much unnecessary, especially with a weighted knob. So again, no negligible difference or damage to the transmission as a result.
