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 design

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.
