# list stops covering every name nobody listed and every name CPython adds later.
# PYTHONWARNINGS is the one that must survive - sixteen scripts under
# jenkins_tests/rpm_tests/p_lve-utils/ set PYTHONWARNINGS=error::UnicodeWarning
# and then drive lve-utils binaries, and fifteen of them assert only on exit
# codes, so dropping it would turn their detection into a silent no-op rather
# than a visible failure. Analysis: CLOS-5881.
