@ -290,11 +290,11 @@ deprecation warnings. Most notably:
all warnings emitted *by* a particular dependency prior to upgrading it
(the third-party ``warn`` module [3_] does provide this, but enabling it
involves monkeypatching the standard library's ``warnings`` module).
* Re-enabling deprecation warnings by default in ``__main__`` doesn't help in
handling cases where software has been factored out into support modules, but
those modules still have little or no automated test coverage. Near term, the
best currently available answer is to run such applications with

* When software has been factored out into support modules, but those modules
have little or no automated test coverage, re-enabling deprecation warnings
by default in ``__main__`` isn't likely to help find API compatibility
problems. Near term, the best currently available answer is to run affected
applications with ``PYTHONWARNINGS=default::DeprecationWarning`` or
``python -W default::DeprecationWarning`` and pay attention to their
``stderr`` output. Longer term, this is really a question for researchers
working on static analysis of Python code: how to reliably find usage of
