I definitely agree with you that the "cockpit" games (racing, space combat, et al.), and things like Lucky's Tale are well served by the current controller, but I don't think it's going serve VR well outside of those niches. Which isn't what you want from the default, bundled controller.
Even just a few years ago most people were thinking that game genre popularity would just map into VR - i.e. Witchers and CoDs would be king. What's becoming more and more apparent is that VR is such a different medium that we need a whole new set game genres and mechanics.
For instance: locomotion with the left controller stick, head movement with the right (which the current controllers are brilliantly adapted for) is such a core controller "idiom" right now, but when applied to VR it's just horrible - a recipe for nausea and disorientation.
If you look at the kinds of experiences that are being developed around Valve's controllers, they're all huge departures from the games we currently play, and the reason is that Valve, as game designers, realized from an early point just how far back to the drawing board we need to go. VR is just too different, with different objectives (immersion), possible modes of interaction, and human weaknesses to address.
