Apple (used to be) very good about getting developers to adhere to the standards. Failing that, I'm hoping for an intermediate layer where developers expose the actions but users can customize the presentation.

Icons are on the way out anyway, precisely because unless there's a strong analogy with a widely familiar physical object, an icon really can't unambiguously convey what it does. They'll still be used for applications but the "replace textual menu entries with little pictures" trend is rightfully dying out.
