+.. important::
+   In the context of ``setuptools``, the introduction of :py:mod:`warnings`
+   (including deprecation warnings) is not considered a breaking change *per se*.
+   Instead it is considered a backwards compatible *communication action* that
+   precedes an upcoming breaking change. This is becauset code

+   execution, unless users explicitly opt into transforming those warnings
+   into errors (e.g., via Python's :external+python:ref:`-W option or
+   PYTHONWARNINGS environment variable <using-on-warnings>`).
