5052-H32 for the parts that are bent, and we use some 6061-T6 when things aren't bent and need to be strong.

No. I'd trust a laser to +- 0.001 or better, and a punch to +- 0.005. Sponsors tend to be pessimistic about what their machines can do.

We don't do it to the extent that we will redesign the part to avoid doing that, or only use them for access. We keep all holes about 3/8" away from any bends, otherwise the holes will blow out and the k-factor will be affected. If there is a hole too close to a bend, we will make it into a slot and break the bend. Some machine shops will leave the holes out and put them back with a mill after bending it, which is a waste of everyone's time.
