I believe what is missing is a way of distributing apps. You face similar issues if you get the C++ source of a random program - there are quite a few build systems in use! However, the compiled program can often just be zipped and shipped, somehow.
The C/C++ ecosystem is a bit more sane, but requires more expertise to fix. As long as you figure out the build process, usually you can rely on the distro packages. For Node and Rust, people really like to use the latest version and not the LTS one for their software.
