Those are all reasons worth considering. Most of them, though, are
reasons why a proposal to include something in the Python standard
library might be *rejected* after being proposed for discussion.


Including something in the standard library needs to be discussed in the
context of a specific proposal. There is a procedure for that: the
Python Enhancement Proposal <URL:https://www.python.org/dev/peps/pep-0001/>.

So, an important reason to consider: Perhaps no-one has developed and
championed a specific Python Enhancement Proposal for including that in
the standard library.

I don't know of any PEP yet which specifies exactly what to add to the
standard library for YAML (and how to ensure it continues to be
maintained in the standard library). There may have been vague requests
for “can we have PyYAML in the standard library?”, but those are void in
this context, because that's not what actually gets the discussion
looking at specifics.

My advice to the original poster: Have a search for past proposals and
see what discussion ensued. If there was no such proposal, try writing
one and championing it.
