Summary: logging module's setLoggerClass not really working

Initial Comment:
The logging package should be modified in a way which
would let users call the setLoggerClass API, and then
consistently get loggers only from that class. 

In the logging package as it is today, the root logger
will always be a logging.Logger instance, and not the
new class specified in the call to setLoggerClass.
These semantics are not clear.

This is an example logger class I would like to use:

class PatchedLogger(logging.Logger):
    def __init__(self, name, *patches):
        logging.Logger.__init__(self, name)
        self.patches = patches
    def handle(self, record):
        #copied from the actual Logger implementation
        if (not self.disabled) and self.filter(record):
            for patch in self.patches:
                patch(record)
            self.callHandlers(record)

And an example "patch":
def EnableTrace(record):
    """
    adds the %(function)s for logging records
    """
    function_name = _get_function_name(inspect.stack()[4])
    record.function = function_name

Can you please explain your use case? Why does the package
have to be modified in that way? Why do you need to be able
to have the root logger be creatable from a custom class?
