I would have thought it up to leagues to set their own rules. Appendix G gives the arbiter the decision as to whether to substitute the clock or not. I could imagine they might invoke the decision not to substitute the clock if their chess knowledge suggested that one of the players was being stubborn and allowing an increment might result in them having to count to 75 before forcing the game to be concluded. It might of course simply be that the Appendix is drafted to be applicable if no substitute clock was available.
Given G4 involves an arbiter decision, a local league couldn't see how to apply it when no arbiter was present. If increments are required and a digital clock available, it's simplest to apply it from the start of the game. If I thought the clock settings or League meetings would support it, I'd be inclined to suggest a move rate of G/88 with an extra two minutes added at the expiry of the 88, with a 5 or 10 second increment automatically triggered only at that point.
