We use argo to manage our deployment of ARC. We recently upgraded to 3.0, where they removed a default setting to ignore the preserveUnknownFields fields being mismatched. From their docs:

The spec.preserveUnknownFields has been deprecated in favor of x-kubernetes-preserve-unknown-fields: true in the CRD v1.

To solve for this now out-of-sync CRD in argo I did enable this ignore rule globally on our argo, but because of this deprecation and the number of people who seem to use argo to manage their ARC installations, I thought I'd contribute back upstream to help ensure argo users show a properly synced ARC by removing this deprecated field.

Here is how our ARC installation looks in argo without ignoring this field while it's present in the CRD:
