The problem with multi-piston is that when you push one of the pistons in, the others move out a bit so you are constantly pushing them one by one until they are all retracted.
Yup. I have no issues with this. I have a tool to open the calipers.

Also, the brake fluid needs to be bled afterwards when retracting pistons with the bleeder open to make sure you get out any air that may come in while open.
This is why I prefer to just open the reservoir where you add fluid and just monitor it. There's no way to introduce air back into the system. My concern is when you mentioned that pushing fluid backwards into the system by opening the calipers was a bad thing for the ABS system. Just wondering if this is true for our car.
