I'm not certain about the best way to address the code smell. Making greater use of the switch statement might not be enough without delegating the additional check to another method for each use.

Tbh, I thought it was a bit of a false-positive, given the offending function is very simple to understand and hardly 'complex', even if it is a bit ugly. 🤷 I have made a limited refactor, without burying the logic in a whole lot of configuration, but if you prefer a different approach I'll do that.
