This issue was brought to my notice today:

and reference was made in the comments to possible obstacles facing stdlib
maintainers who might wish to use logging in the stdlib and in its unit tests.
From my perspective and as mentioned in the logging documentation, library code
which uses logging should add a NullHandler instance to any top-level logger,
which will avoid any "No handlers could be found for logger XXX" message if no
logging handlers have been set up.
I've done that before in my own library code, then quickly realized that it was
a bad idea. Adding a NullHandler silently prevents logging.basicConfig() from
working.
Only on the root handler. Forget this bit of my argument (and the statements
that directly follow from it). The rest of my argument should stand on its own,
though.
