[Question] Exposing rx subjects from presenter to Interactor ?

I was thinking whether there is any draw back in exposing rx subjects from the presenter to the Interactor. Taking an example of loading all employees in a tableview

Presenter:

protocol EmployeeListPresentable: Presentable {
	 var empSubject: PublishSubject<[Employee]>{ get set} // Exposing rx subject
}

Interactor:
//Assuming here employees is an array of Employee objects
self.presenter.empSubject.onNext(employees)

This is more convenient at times compared to calling a function. for eg:

protocol EmployeeListPresentable: Presentable {
	 func updateEmployeeList(_ employees:[Employee])
}

as the subj is already bound to UI and reloading takes place automatically.

The issue names no repository files, tests, or entry points to inspect. Start by locating the presenter and interactor contracts for the employee-list example and review existing RIBs guidance on presenter-to-interactor boundaries. Done would require an agreed architectural direction, with its trade-offs documented and an identified implementation scope.
