I hear you joebag. Here's one way you can challenge it.
Simian? Back me up if I'm right. Or just add your 2 cents.
This is fall protection, and would have to withstand a man falling onto it. Now remember the term "crash deck" is obsolete, they technically do not exist without design as you would have to do a lot of calculations to work out what you would need, even just working out what impact a falling brick would have is tough (so I'm told, I'm no mathematician).
So, these new things. What force can they withstand? If they are technically, a crash deck, they would have to have some detailed instructions and calculations telling the user exactly how far it will protect someone!
Also remember that WAHR applies to everyone, not just us. If we have to put up with this cr*p of prevention over protection in the extreme, then so can the other trades.
It also occurred to me today, when laying out beanbags for the brickies to work off the completed scaffold, that this is technically not working properly to the WAHR, as beanbags are protection. Technically brickies should have a handrail going around the inside of the brick work to stop them falling into the building...... They would also have to wear a harness as they are working at height.
