Indeed (although migrating the playbooks to 2.x isn't that difficult).
Upstream has an extensive test suite and is pretty fast in addressing the
few bugs that occasionally slip through, not to mention the security fixes.
I've been using Ansible's stable releases privately for quite a while (via
MacPorts), without ever experiencing any serious regressions - even minor
annoyances have been rare.
I would argue that is not the case for a sufficiently large project (such
as openshift-ansible). We hit quite a few problems when migrating from 1.9
to 2.0 and to a lesser extent 2.0 to 2.1. The 2.1 to 2.2 migration went
smoothly (we had previously fixed the templating deprecation warnings,
otherwise we would have been bit), but we've hit regressions with 2.2.1.
I agree that the Ansible team is very responsive to fixing issues, but the
architecture changes from 1.9 to 2.x introduced breaking changes that
affected playbook parsing and breaking plugins.
Since Fedora already makes the effort to provide the current Ansible
releases in EPEL, it would be a pity not to take advantage of that.
I agree, however there would need to be a transition period for projects
that can't respond immediately for breakage related to an Ansible update
(moving to using a locked version in a virtualenv) or have other
extenuating circumstances (openshift-ansible for example has a callback
plugin that provides a friendly error for Ansible < 2.2 or Ansible !=
188.8.131.52, though it looks like we'll need to add a test for 184.108.40.206 now as
well). That said, the OpenShift jobs already use a virtualenv.
