We do not support running neutron on bsd (e.g. macos) systems, so the function has no reason to exist. The only user is neutron test suite and it's proposed to remove its usage there too: If5e06dcf3a323692137d2c7cbb8ca725d9d7d821 Note: This patch reintroduces debtcollector dependency to handle the deprecation process.
