Most Cat A certified helicopters with training mode will have similar limits if you asked the makers - the FMS only ever describes use in Cat A manoeuvres on all the types I’ve flown. It’s driven by the certification specs. The bare minimum is the take off and landing phases so that’s all they test. Customer demand might make them test elsewhere but I suspect that rarely happens as it’s not terribly marketable. I feel you get the most training benefit and meet the Appendix 9 LPC requirements below 1000ft anyway which is where it’s been tested so I feel perfectly comfortable using it in these conditions. Confined areas PC2 - maybe not.
I wouldn’t use a physical block on the collective by the way. There isn’t one for real and much more fun/realistic to mimic a suitable audio tone if they exceed your nominated power limit.
