At a later point this will indicate whether some FunctionObject "has a [[Construct]] internal method" (separate from the current FunctionObject call() / construct()), to help with a more spec-compliant implementation of [[Call]] and [[Construct]]. This means that it is no longer relevant to just NativeFunction.
