I don’t understand what you’re talking about. Literally all common interpreted languages adhere to Unix standards—they take arguments, use environment files, handle input and output streams, and load libraries.

Their single advantage over Python is that they are able to work fine without virtual environments, as they just load libraries from a relative path: That way, you can copy-paste a project directory, move it to another system with a copy of the interpreter binary, and… run the software. There is nothing clever about that; I’d even say Python's way of magically configuring a shell just to be able to locate files is the "clever" solution that nobody asked for!
