What is the point of adding new layers in project settings, and how to use them?

I've noticed that you can add new layers beyond the base 20 ones, whether for physics or rendering.

I fail to understand how these can work with the bit masks, and they don't show up in the editor interface. To use the 21st layer I've added, I tried doing set_layer_mask_bit(1 << 20, true) on a MeshInstance and set_cull_mask_bit(1 << 20, true) on my camera, but to no effect.

What is the purpose of these custom layers and how do you use them?
