There is no change in behavior by https://review.opendev.org/c/openstack/tempest/+/686306 , 'member' role was assigned to each user previously also on setup use the devstack installation.

its devstack set the 'member' role in CONF.auth.tempest_roles

and Tempest add this role to each user irrespective of test ask for other roles or not.

Also to tests the new RBAC default like 'reader' role devstack should not set the 'member' role as default in CONF.auth.tempest_roles.

adding devstack in this bug report.
