And it would look like a 20MB+ file just for a simple 1KB Python script...

For Windows at least, I'd prefer to have some app-style installer generation (e.g. http://pynsist.readthedocs.org/en/latest/) which, combined with the embeddable Python distro (new for 3.5.0b1 in case anyone missed it), can simply extract everything into an install directory and run it from there. None of the items on the list above are needed for or would help with this.

(Some other Windows-specific advantages of the latter - installers get special compatibility treatment when the OS does stuff to break them, modifying official Python binaries breaks the signatures, signed executables are fully scanned before running (slow if the file is big), IT departments know how to deal with installers and users know how to deal with installed binaries, and probably more.)

Alright everyone, back on topic now unless you want to rename the thread :)
