Flux kustomization finalizer is not domain-qualified

[jaxels10]

When installing the newest version of both Flux and the Flux CLI and running flux install on a cluster, I have run:

 flux create source oci podinfo \
    --url=oci://ghcr.io/stefanprodan/manifests/podinfo \
    --tag=6.6.2 \
    --interval=10m

and then

  flux create kustomization podinfo \
    --source=OCIRepository/podinfo \
    --target-namespace=default \
    --prune=true \
    --interval=5m

The kustomization that is created from this is:

apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
  finalizers:
  - finalizers.fluxcd.io
  name: podinfo
  namespace: flux-system
spec:
  force: false
  interval: 5m0s
  path: ./
  prune: true
  sourceRef:
    kind: OCIRepository
    name: podinfo
  targetNamespace: default

However, the kustomize controller warns:
"metadata.finalizers: \"finalizers.fluxcd.io\": prefer a domain-qualified finalizer name including a path (/) to avoid accidental conflicts with other finalizer writers"

I would like to solve this issue myself and create a pull request, but I need a little bit of guidance on what the path should be (and if you even want this to change). I would also investigate whether this is an issue on more resources than just the kustomization. Please provide me some input and I will help contribute.

We have no plans to address this, Flux APIs are GA and changing the finalizer would be breaking, you can just ignore the warning.
