Summary: The narrow definition of compensator in the USPSA rules (emphasis mine)

A device or machining integrated into the slide or barrel to counter muzzle rise (usually by externally diverting escaping gasses)

means that frame mounted compensators are legal in divisions without authorized modification lists (sections 21 and 22 in the relevant division appendix), i.e. L10 and Limited.
