molecule on stable/wallaby are broken

Looking for "stream-molecule" all is red:

Especially:

We were also pointed to this additional error:
File "/home/zuul/src/opendev.org/openstack/tripleo-ansible/.tox/py36/lib/python3.6/site-packages/openstack/utils.py", line 13
    from __future__ import annotations
                                     ^
SyntaxError: future feature annotations is not defined

Which points to openstack-utils.

(though here, I don't find it in the logs so far).
