What problem are you facing?
With the recent design for Observe Only resource, we expect to have the full state under status.atProvider, i.e. status.atProvider should be superset of spec.forProvider. See the design for further details:
https://github.com/crossplane/crossplane/blob/master/design/design-doc-observe-only-resources.md#api-changes---full-state-under-statusatprovider
How could Crossplane help solve your problem?
Adjust the schema of all managed resources accordingly and update controller logic so that the status is populated during observation for newly added fields.
