Motors that trap the heat in will fad power as they heated up and eventually died.
The the motor technology in the AEG and PTW are not even advance as the ones in RC cars. We are now racing brushless for many years, and yet the airsoft guns are still brushed.
Run the grip off a PTW and feel the head from the armature after 50 some shots, it is very hot to touch. You need to get rid of that heat not trap and seal it in the grip.

You are not going to dissipate the heat from a PTW motor by drilling holes in the endplate, or even leaving it open. Run a PTW for a few hundred thousand rounds and get back to me.
What you will do though is introduce debris that will kill it. You have never owned an RC motor as open as a PTW motor, nor with the tolerances between motor and grip, nor between motor components.
Your reasons are transplanted from irrelevant sources.
