Hi, my thoughts are it would be just one more warning horn to be dealt with, or not.
I flew a twin seat glider in some aerobatic manoeuvres, and hardly looked at the instruments. It also had no stall warner. Then when I tried the same manoeuvres in an aerobatic power plane, the stall warner was constantly sounding... Pulling into and out of a loop, doing moderately tight turns, and intermittently whilst in turbulence.
I said to the Instructor that the stall warner was making a lot of noise, he agreed and said we should just ignore it... It's just one more distraction, and one of the reasons they are not fitted to gliders.
Maybe Data Mining is a useful tool in situations where decisions can be made in a time span of a few weeks, but to expect pilots to make split-second decisions at the drop of the electronic hat, may be just too much data at the wrong time.
