Right, this was my reasoning as well: if someone has gone to the trouble of factoring their code out into a support library, it's reasonable to expect that they'll also write at least a rudimentary test suite for that code. (The one case where that argument falls down is when they only have an integration test suite, and hence run their application in a subprocess, rather than directly in the test runner. However, that's a question for test frameworks to consider: the case can be made that test runners should be setting PYTHONWARNINGS in addition to setting the warning filter in the current process) By contrast, I have quite a bit of __main__-only code, and I routinely use the REPL to check the validity of snippets of code that I plan to use (or advise someone else to use). Those are the cases where the status quo sometimes trips me up, because I forget that I'm *not* getting deprecation warnings.
