In PR 5640 (https://github.com/python/cpython/pull/5460), a warning was added that importing ABCs from collections directly is deprecated and will be removed in Python 3.8, but they have not yet been removed and the warning is still active.

If they are going to be removed, presumably it needs to be done before the feature freeze at the end of May, otherwise, in the meantime, I think the warning needs to be updated to say that it will be removed in Python 3.9.
