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.
