I tried to create a Drone plugin that was reusable (as an account-level template) that could be reused within a pipeline that has CI and CD stages. I discovered that Plugin Steps are only supported in CI stages. The workaround provided was complex - create a Step Group with a Containerized Step and then within that you can include CI steps such as the Plugin Step.

I think that is unnecessarily complex and would like to see Drone plugins supported in CD stages natively as that would make it much easier to build and maintain them.
