Ah, I misunderstood what you meant, then. I thought you were advocating to move the built-in short-help support to know about and explicitly react to "-?", and somehow forgot that it "works" more or less already. The fact that "-?" already works for most things is good, but the transition pain still remains, as what's costly is to transition people's expectation (i.e. "'-?' and not '-h' is the way to get short help from any subcommand"), not the implementation to fill the gaps for those that do not yet support '-?', I am afraid.
