Considering the sizes involved, and dT5 likely being the smallest resin disc product, I would opt for caution. While robust, they are not impervious to shattering / cracking / breaking if you put considerable pressure on them, though much more than glass. The problem is the size / dimensions of discs create a huge flat surface area which can easily act like a lever, or be acted upon by much smaller points of force which would make those points of force into fulcrums. The thickness of discs and resin products is kept as low / thin as possible, which directly impacts the ability to withstand exactly this scenario.
Considering this, I personally would not go for P0 (palm side) except for anything, except for maybe a very small magnet.
