This is the reason I exclusively use pockets not holes. This works great for 3d-printing but wont work as well if you intend to export to CAM systems that can use a drill to make the holes.
Why's that?
I think the hole feature directly translates into drill instructions in compatible output formats. Where pocket just modifes the 3d shape, not that you couldn't use a drill but it would need more software to spot the hole like shape and use a drill for it.
