The constraints extension in PEP 459 recommends flagging extension processing as required, otherwise it's possible for unaware installers to silently skip the compatibility checks: https://www.python.org/dev/peps/pep-0459/#the-python-constraints-extension Installers offering the ability to opt in to ignoring environmental constraints is one thing, ignoring them through lack of understanding the extension is something else entirely.
