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.

Cheers,
Nick.
