You would think after all these years, and changes in Gerber and Excellon standards, that somewhere along the line someone would have said "Hey, we need Gerber and Excellon notation for slots and arbitrary shape cuts".
Nope. Rhetorical question: If apertures can be embedded in Gerber files, why can't other primitives, such as slots and arbitrary shapes?
