Having the shared library that can be replaced by itself, instead of deploying N things, is nice. Not sure it's the end of the world, but it's nice. On the flipside, though, this is probably a case where using something like Rust could be excellent: stronger language support for eliminating entire classes of bugs but also able to be compiled down to something that can be a shared library. I'm not an ML expert, but reading about the things the Mirage project has done related to TLS, leveraging OCaml to provide compile-time guarantees, sounds very exciting. Rust feels like it could be that bridge. Start rewriting core libraries in it: cleaning up old code, removing dead code, avoiding bugs by virtue of the language/compiled, in one fell swoop.
