Fill with what stuff exactly?
The only thing I want to inherit from the parent process is its cwd and environment variables, even those are often overridden. The rest can easily be passed explicitly through other channels like pipes or command line arguments.
Back to the example from the article. It makes no sense that a git-subprocess forked from a web server need to have any process state inherited from the web server.

Yes, exactly. Cloning, as a process creation primitive, is the one thing that doesn't need to be concerned with other stuff.

That's pulling in a whole load of assumptions that are distinct from process creation. You can have processes in an environment that has no concept of file system or persistent storage at all.
