Of course... and I'm not suggesting that every app in a linux distro should be as such. You can dynamically link with Rust, Go, etc. That said, for one of the 3-4 GUI apps that most people use, the distro process tends to leave people with relatively old versions missing critical bug fixes or features.
I tend to keep my host OS pretty bare, and most of my runtime apps in Flatpak and the stuff I'm working on in Docker.

Do you have experience with that, or do you say it because you believe it's possible? Genuinely interested, because I have been looking into it and my conclusion was that it does not really do what I expect from "dynamic linking".

No, but it has to wait for each developer of each binary individually. Instead of relying on a team of maintainer, you now rely on all the developers.
"Self-update" isn't something magical: someone has to do build the new version and ship it. With static linking you still have to build and ship for every. single. binary. With dynamic linking you just build and ship the one library that everybody depends on.
