Small cutouts like those in the pads you are describing are usually restricted to slots or cutouts with a radius at each end or corner. This is because they are usually created using spinning drill or router bits. There are many ways to specify slots unfortunately none are as simple and

Dennis, the main benefit is for SMD designs with components on both sides. If the panel is laid out correctly (i.e. symmetrically as flipped), the assembly process can use one set-up and run the boards through the one line twice. During the first pass board A has it's top side components

Having alternate boards flipped in a symmetrical layout means that only one solder paste screen is required. Also, the same placement control files and machine setups may be used, since the assembly panel looks the same whichever side is up. In really high volume it's not so much an issue, since
