It appears you may be confusing POSIX's (1.5 Terminology)
*shall* (mandatory) and *should* (recommended):

"*SHALL*

For an implementation that conforms to POSIX.1-2017, describes a feature 
or behavior that is mandatory. An application can rely on the existence 
of the feature or behavior.

For an application or user, describes a behavior that is mandatory.

*SHOULD*

For an implementation that conforms to POSIX.1-2017, describes a feature 
or behavior that is recommended but not mandatory. An application should 
not rely on the existence of the feature or behavior. An application 
that relies on such a feature or behavior cannot be assured to be 
portable across conforming implementations.

For an application, describes a feature or behavior that is recommended 
programming practice for optimum portability."
