Your apt update would still be huge though. When the dependency changes (eg. a security update) you’d be downloading rebuilds of 20 apps. For the update of a key library, you’d be downloading your entire distribution again. Every time.

Oh, well yeah, statically linked binaries have that downside. I guess I don't think that's a big deal, but I could maybe imagine on some devices that are heavily constrained that it could be? IDK. Compression is insanely effective.
