When importing an ABC from the collections module in Python 3.9 there is a warning that this is deprecated since Python 3.3 and will stop working in Python 3.9.
Should this warning be removed and lead to an ImportError?

It's a work-in-progress: see bpo-37324.

Please see discussion at bpo-36953 and bpo-37324. It's currently blocked by Jinja that doesn't have a release with the fix to be used in CI.
