When a repair requires soldering, it significantly reduces the number of people who can do that repair themselves. I can do it, but most of my non-technical friends could not, even though several of them could replace a hard drive or even a DIMM in their desktop PC.
On thinking about it more I agree with you. A very simply soldered thing is maybe ok, but the vast, vast majority of soldered things are no-gos for repairs for non-pros. It's too easy to damage components and destroy the board, even if you know how to do it. If the Framework required soldering, I'd be very critical about it's repairability/modularity, so I'm being inconsistent.
