Looks good to me, though a couple questions:

1. Should we just install the operator as a normal openshift operator (via OCM) as part of our cluster turn-up, treating it like any other OpenShift provided service/dependency? If there's no configuration going on, why is it necessary to install via the Helm chart? And if we do want to install it via the Helm chart, can we document why in the PR description or a README.md, so we know why it's here?

Other than that the configuration looks reasonable to me

I don't think so, it was there for every chart, didn't want to break the convention
