It gets mess not just in that way but also someone can have a weird LD_LIBRARY_PATH that starts to have problems. Statically linking drastically simplifies distribution and you’ve had to have distributed 0 software to end users to believe otherwise. The only platform this isn’t the case for is Apple because they natively supported app bundles. I don’t know if flat pack solves the distribution problem because I’ve not seen a whole lot of it in the ecosystem - most people seem to generally still rely on the system package manager and commercial entities don’t seem to really target flat pack.
