DRC – support for holes in inner corners of board outline

Description

To realize a sharper corner / smaller radius than the diameter of the board outline cutter/router can provide, a small non-plated hole is drilled in the corner before the edge cut is routed. These holes in the footprint currently cause DRC errors.

Is there a way to avoid them? If not, could these kind of holes be allowed to touch the board outline? They are quite common, and it would be nice to have clean footprints, without the need to add exceptions for them, or switch the DRC check completely off.
