Setups with arbiters especially. I know it's a relatively new feature
still, however all of the tools for managing & manipulating dist-rep
layouts are geared for standard bricks. It's very easy to accidentally
convert your arbiters into full rep 3 bricks.
Luckily, most situations where you want to grow your cluster from a basic
setup, you'll be converting to true rep 3 anyway.
