Ben Griffin <ben at redsnapper.net> added the comment:
Having looked at the code, I believe that it is best NOT to interfere with the 'default_section' value of the class, as it is used as a proxy to _defaults, whereas the section parameter of get() is easily extended.
The actual changes are all to the method _unify_values, and it is trivial to extend that method to allow for multiple dictionaries to be passed to _ChainMap.
This is what I did in PR-18791
