Not sure we need to bother having a debate about what should or shouldn`t be done.
Most are disagreeing , you feel differently , to each their own , its your car , you can cut whatever you want. If you have an accident its on you.
But i will mention that most , not all , but mos have experience with the focus and its parts , so i would heed when multiple people are saying the same thing.
But in the end is your choice.
Your car , your choice , do as you will
