Because I have better programming languages which, despite being able to interact with the system and its commands, don't pretend to be one with the system. As a result, the core high-level language constructs mesh better, because they're not trying to serve two goals at once. The power and usefulness of a given language is often the ability to serve multiple goals at once. Python as tool is cool specifically because of a large-ish but accessible-ish library covering a everything from regex-ex to a web-server. This project might not serve the goal of writing high level programs and interacting effortless with the command line/system. But I don't one should automatically dismiss the goal of making stuff-glued-together look like a coherent whole.
