[issue39540] Logging docs don't address the creation of multiple loggers when a hierarchy is provided

[Vinay Sajip]

That's an internal detail. In fact loggers aren't created for all loggers in the hierarchy - PlaceHolder objects are created internally for hierarchy ancestors, and converted to loggers if needed. The printout from your linked Stack Overflow question shows this.

This is not documented because it's internal implementation detail. How the dotted-name hierarchy works is documented.
