I don't see how data recovery is an issue. You should be backing up off-site and locally anyway. Why would you optimize for the specific case of most of the laptop dying but not the SSD? It's more likely your laptop will get stolen or lost or dunked in water or burned in a fire. The soldering will make no difference in that case. Use backups.
there is ZERO benefit to users of soldering an SSD or any other part. Its done purely for profit.
Stop conflating the issue with backups, the 2 have nothing to do with each other. Even if you take regular backups you can and will lose critical data when any $5 part on your $3-4k machine goes bad.
