Not really; I had an issue that silently broke renewals. When I found the open issue that corresponded to it the maintainers were herding people to cert-manager. There are a lot of issues where they are doing that (besides very obviously at the top of the README with warning symbols). At the very least it's eventually going to break on newer versions of Kubernetes. Maintenance-only != LTS.
