For https://github.com/pulumiverse/pulumi-acme, I did not add .github/workflows because it seemed that there is automation to generate those artifacts, is that correct?

No, you will have to follow the steps from this document to put the initial release workflow in place yourself: https://github.com/pulumiverse/pulumi-acme/blob/main/deployment-templates/README-DEPLOYMENT.md The automation you might be referring to is something you probably saw for the providers managed by Pulumi themselves. This unfortunately doesn't work (yet!) for thirdparty providers (including Pulumiverse).

ahh, that makes sense, yes it was that. Np, I'll get it added.
