👋🏽 Argument of type 'null' is not assignable to parameter of type 'boolean'. Why can't we stick with false?

Sorry, me again with some feedback. I'm trying to understand why we go for a double type declaration here. What's the scenario where setting this to false (instead of null), and removing line 29, that it would still show undesired behavior?
Happy to merge this PR, just trying to wrap my head around why this would work.
