Layers have less "incalculable risk" when you design the layers yourself for your needs and according to your logic.

Don't use layer setups other people designed verbatim; take inspiration from them.

For example, my own ergo keyboard has no dedicated backspace button; instead I chose to have fn-M (a thumb function key) and it's actually better for me than reaching for a true backspace key.

I would never expect anyone else to be able to use my keyboard though.
