Why? Having a bundled Python version - any version - means that you can ship Python scripts to others. Not having a Python version bundled means you can't ship Python scripts at all.

Sure, you can still technically ship them, but now you need to tell users "just run this simple scipt!... after you install Python X from place Y, and now you'll have multiple Python versions installed, so here is how to keep them separate, and [...]". Or, you can bundle your script with a whole Python installation!

It’s only really feasible to ship APIs in an end-user operating system that can make forward binary compatibility guarantees.

Python doesn’t make a sufficient guarantee of forward compatibility for either scripts or its C-linkable libraries. This means that, unless an OS vendor does a bunch of extra maintenance work on the Python that they ship, an application built in or making use of the Python shipped in one version of an OS may not run on a subsequent version of that OS.
