Just an idle thought - how could you implement a stick-shaker on an Airbus-type side-stick?
That doesn't seem that easy, compared to a conventional yoke, at least.
Clearly the vibrational aspect of the 'shaker' is significantly important, since the aural aspects appear to be relatively easily dismissed. However, unlike a yoke, there is no significant mechanical structure to attach the shaker drive to.
If the SS were back-driven then it would be comparatively easy to implement I suppose... but it isn't.
