It seems semantically wrong to mark a Revision as "Available" == False for any issue with finalizers.
In general I would not report any internal error as a Status Condition.
If we want to show individual errors to users we should publish events on the resource.

Totally agree that this is likely the wrong type for this. I would expect to come back and clean this up prior to GA once there is a formal design on status handling.
In the meantime, I do think it is an important UX concern to tell the user something in a place they are likely to see it.
If they've deleted a CER (or an agent has on their behalf), but the finalizer isn't being removed for some reason, it would be a bad to UX for the CER to just... have no update. It would look like we just aren't reconciling it.

Re-opening here now that poc-boxcutter PR is merged
Original PR: thetechnick#5
Description
A few small fixups and comment additions to help remember follow-ups:
Reconcileandreconcilemore consistent between CE and CER reconcilersReconcilereconcileNOTE: There is still one major difference: CER updates finalizers as separate patches and continues reconcile logic. CE updates finalizers and requires re-reconcile to continue beyond. The CER logic may cause issues where the next reconcile sees a stale resource version (from finalizer patch) because the status update event isn't seen by our informer in time. This ultimately leads to reconciling a stale CER that manifests as a conflict error in our logs that is often a red herring for users trying to troubleshoot issues in controllers.
Another noticeable difference is that CE uses controller-runtime Finalizers helpers, and CER handles things manually.
Changing this broke unit tests, so I decided not to leave that change out to keep the PR scope small. I'll make a separate PR that focuses just on finalizers.
