TE/TC TX300 subframe removal?

Wow quite a lot of material removed. after opening up my 2014 I've decided to stick with stock on this machine (2017 TX300). I want the thing to remain docile to fit my new old guy style of riding. I would advise finishing/smoothing the cuts and rounding the corners to prevent cracks from forming on the sharp edges.

plus if you want it less docile for a ride, put in the red spring
