There is a cheap version of those on SJS https://www.sjscycles.co.uk/brakes/0-suntour-selfenergising-se-cantilever-brakes-rear/ No idea if they're any good mind.

People on the internet say they're best for tandems and things where you need massive stopping power, otherwise they're way overkill. But I imagine serious bikepacking/monstercross/a full touring setup is approaching similar levels of stopping power? Especially if you've got 2" knobbly tyres for major traction.
Anyone used them? Might chuck a set on my rear cantis
Mm that suntour brake is nice though, I'd like some of those
