The deletion of an HCP ROSA cluster can get stuck if it gets into a state were the request serving nodes are deleted, but the deletion is pending on API requests, see OHSS ticket for an example. Apparently HCCO will never change the CloudResourcesDestroyed condition to true since the api server of the hostedcluster is gone, which can happen when timing out. See slack conversation for details
