This is a great move. It will be two lines of code and two minutes to install the interpreter you need, and you will no longer be tied to a global, possibly ancient system version. Likewise, you won't have your own installed applications break on update because (for example) python2.7 was EoL and dropped from the OS. Installing your own instance of python or ruby should be two lines and about two minutes assuming a decent internet connection.
