Lo que suele suponerse

An option configured with an optional value and a custom argParser coerces a fallback value through argParser when the flag is invoked without an argument on the command line.

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

Contrato

• Option.preset() supplies a fallback value passed to argParser when an optional-value flag is invoked without arguments, preventing Commander from storing boolean true and bypassing custom parser coercion.
• opts() contains boolean true instead of a parsed number when an optional-value option lacks a preset and is passed without an argument
• opts() retains the default value when the optional-value flag is omitted entirely
• opts() contains the parsed custom argument when the flag is passed with an explicit value
• accumulating option collectors append preset values on valueless flag invocations instead of having the entire accumulated array overwritten by boolean true
• options configured with choices validate against preset values rather than assigning boolean true outside the allowed choices list
