Just a rough idea - not sure whether patches 9 and 10 should be
deprecated before removal. Maybe someone might still use them for
emulating older systems?

If you feel it needs to be deprecated first, I could add these two
properties to my series about deprecated property support (v3) -
v3 will take some time.
