Possibly Extraneous Profile Option Assignments

Good day,

I am building a draft of a new Operating Unit for my Organization and find that existing Responsibilities have Profile Options that documentation hints may be irrelevant. These are HR:User Type and HR: Security Profile, both assigned to numerous non-HR-related Responsibilities in exiting OUs. It seems like these may have been initially assigned to an initial set of Responsibilities, due to being conflated with similarly named MOAC-related Profile Options. These may then have propagated forward because "they must do something, right?"

Is there a valid reason for having these applied to, say, and Order Management or Inventory Responsibility? If not, then does this extend to the HR:Business Group Profile Option?
