Not seeing another interpretation here but maybe I'm missing it? It's valid but I'm not going to agree with it at all.
As I said previously, this additional tracking is for training that needs additional sports-specific data. Everyone gets the same always on steps, sit/stand, and heartbeat tracking.
Because in the view of apple, manual labour doesn't count for anything "specific" even if it is a bigger, longer and more intense workout than something you would likely get at a gym. Which is right back where we started. If the watch can do it all automagically there isn't any need for 'sports specific' tracking, right? Imagine being a furniture removalist and how you can set your watch to get whatever you get from setting it for your gym session?
And yes, you're probably aware and it also kinda beside the point, game-ifying manual labour is a thing many people do but also, seemingly, not using an apple watch to do it.
There’s a thriving app marketplace, if you’re so convinced that there’s a market for your working man’s tracker, please feel free to go make tons of money.
It is exercise to move furniture. It is exercise to go for a run. If there is something worth tracking on the latter its highly likely for there also to be something equivalent for the former. Apple knows its market isn't manual laborers and ignores whatever interest they may have. There's no money in it.
Best of luck to you.
This place is supposed to be better but all places like this degrade over time despite @dang's tireless efforts.
Best.
