Environment variables are just like a configuration file that's automatically opened by the OS when a process start and automatically parsed as a set of named strings by the libc. In the many cases where one does not need more complex data structures than that, then to introduce a config file is just making things harder. That being said, I wish envvars had namespaces of some sort.
