So...we are all agreed then?
a. Jack Stall occurs when the limits of the designers chosen hydraulics jacks are exceeded by the aerodynamic forces of stalled rotor blades.
b. Both roll &/or pitch control (or both) are lost for the period of exceedence.
c. It is violent, potentially fatal & probably reduces the airframe & component fatigue life &....
d. Can, like LTE, be significantly reduced (even eliminated) with more robust design efforts.

My 2cents:
Risk management is the very essence of being a pilot (esp a helo pilot).
I agree with Nick entirely but the manufacturers also have valid points. Eg: Mr Robinson designed a the R22 to commute from A to B. If you're throwing it around mustering or deer hunting then you must bear some responsibility if things break.
RBS and Jack Stall are not always the result of deliberately being a cowboy. Scooting around a ridge into a string wind is a common cause.
(other factors are weight, blade angle, rate of control inputs, temperature/humidity/density altitude and TAS)
Perhaps the compromise is that if you're NOE at 8000ft, ISA+20 and dodging gunfire in the Afgan mountains......you surely deserve powerful hyd jacks.
If you're helo was designed for flying tourists on city tours of NYC, then I you should be flying within the most limiting factor (be that mechanical or crew experience).
So where does that leave us?
Should manufacturers be providing a comprehensive list of tasks, locations or environments that void the helos warranty?
btw: The Huey jackstalls with carefree abandon. (Euro vs USA isn't a rivalry worth anyones time/effort).
Nick...I can only agree with your points but following that same route:
a. We'd all be flying twin engined helos that can hover at MAUW on 1 at ISA+15 'just in case' the engineers failed us and,
b. We'd all have anti-icing and full IFR avionics just in case, in poor weather with poor airmanship, we failed ourselves?
