Huh, I'd have guessed the opposite: that a laser, optics, and a piezo vibrator would be easy to integrate, while a MEMS gyroscope would be much harder. I ask anyone who gives the slightest hint of familiarity with the field because I suspect that my surface-level understanding is just missing the juicy photonics challenge that's roadblocking integration. The alternative hypothesis of military heel-dragging (similar to the case of bolometers) is much less exciting, but verifying it would at least allow me to stop poking around :)
