I could see this being used for fitness tests for cross country skiers. A very common exercise is med-ball slams. These aren’t a perfect analog to double poling but definitely close.

Being able to track your one rep max force you can generate could be an interesting metric especially for sprinters

100% agree. And the issue with med-ball slams is they also can just be dropped in a testing setting, and the only power needed to be generated is on the "up" cycle. I wouldn't even trust my own med-ball slam benchmarks from one month to the next, as I'm not confident I slammed them with the same intensity.

I'm curious though, wouldn't a Concept2 ski-erg be the best machine for that job?

>track your one rep max force [...] especially for sprinters

Yeaaah that's the ticket =) One level of abstraction higher: you can think of that 1RM as the leftmost point on the max power curve, i.e. max force you've historically generated, from 5secs all the way to e.g. 60 mins [1].
