What’s the point of this comment? And do gliders really “fall out of the sky regularly”? I haven’t checked the statistics, but that’s certainly not the impression I have.

Stall/spin accidents in gliders are AFAIK no more prevalent than any other GA type.
It’s also impractical to have a stall warner in a glider, since (especially on a weak day) you spend a lot of time thermalling slow enough that a stall warner would be going off constantly.

The latter part I would say rather critical. Non working stall warning would be a no-go or at the very least an item requiring extreme caution.
Depends on the aircraft.
For some aircraft, the stall warner is a required part for the certification. An inoperative stall warner makes the aircraft illegal to operate as it’s required.
For others not so much. My aircraft doesn’t have a stall warner, but on the other hand it’s quite easy to tell when you’re approaching the stall. For a typical approach to a stall (non-accelerated), the controls get light and sloppy, the sound of the air going past the fuselage almost dies away completely, and you start to feel a bit of buffet just before the event. A stall warner would be a bit superflous.

Plus you would distrurb airflow with tab sticking out from leading edge.
Btw stalling and spinning glider is much easier to recover than common powered aircraft.

I did some stall/spin training a few years ago, simulating a stall off a winch launch – so only about 900 feet for the exercise. We only lost 200 feet in the exercise (but it was very eye opening – as intended – because a low altitude stall looks a lot different to a high altitude one, because you can see the ground coming up to smite you).

Indeed 
New stall warner switch received from Socata – the special version with the longer paddle for the TKS system
With an EASA-1 form of course. It is a “Burgess” one and I estimate it is at least 20 years old
The operating force is perhaps 2x greater than the old one was, hence my original Q.

Have I missed something, this is a joke, right?

Another joke?
Depends on the aircraft of course. If yours is a hang glider, probably not But I reckon the stall warner is mandatory on a TB20 and most other GA types, but don’t have a reference.
