There are many reasons why a particular library may not be included in the
standard library:


1.  Perhaps nobody has thought of it.

2.  The author of the library refused to allow it, or demanded
    conditions which the Python developers either cannot or will
    not meet.

3.  The library is under rapid development with a release cycle 
    faster than Python's standard library.

4.  There may be technical reasons (e.g. code quality, external 
    dependencies) why it isn't added.

5.  There may be no consensus among the core developers that this
    library is important enough to include.

6.  Or no agreement about which library to use (if there are
    more than one).

7.  The library is for too small a niche to bother.

8.  There may be problems with the legal status of the library, 
    including legality of the software, copyright, patents, etc.

9.  Or it may be only available under a proprietary, closed-source
    licence that is incompatible with Python's open source licence.

10. There may be nobody willing to maintain the library once it
    is accepted.


I'm not sure which ones apply to YAML. If I were to guess, my guess would be
either 5 or 6.
