I guess one can work around the lack of dynamic linking in a language like Go on the package manager and/or distro level (though some established distros and package management ecosystems, which I very much hope will not go away, will have it harder to adapt than others), but I really would like to make everyone think about whether we should...

Imagine a Debian archive (that is, a few tens of thousands of packages with source, build recipies and binaries for multiple architectures available) with only static linking on the table. You got a few hundreds to thousands of those packages installed on typical, real-world Debian machines. Then, a central component like zlib or OpenSSL gets an important patch. This triggers hundreds, if not tens of thousands (transitive library .so dependencies are a thing after all, and you want to have all your supported arches covered) of rebuilds across the archive. All users will have to re-download and re-install all resulting upgraded packages they have installed.

With increased sharing of source code (i.e., when following "don't build your own crypto!" and other generally useful mantras by re-using existing codebases) and only static linking on the table, this kind of problems gets really, really bad really quickly for large-ish software archives. Kinda like with log4j in the Java ecosystem, where each app is used and event expected to dragging all its runtime dependencies along on its own.

In the dylib world we are living in right now however, users get a single updated package, and upon the next restart of an application linking against it, they're immunized against the bug. The reduction of churn is nigh-unfathomably massive.

If your systems generally only run a single application, and there's a dedicated ops team at the top (or bottom - it's a matter of perspective, I guess :)) of a monorepo world with each dependency fully vendored in, and an "intelligent" build and deployment system atop it all that will take care of gracefully upgrading everything everywhere upon such routine patching, I can see how statically linking everything reduces the amount of potential pain points upon deploying stuff. For the significant portion that makes up the rest of the world, they generally don't have such luxuries, and will be a lot worse off. Especially established and wonderful Free Software communities like Debian or Fedora. I think that would be a huge sacrifice to make.
