I'm thinking about looking into more automation where I'm at, one part I would like to try out is creation of default setups when initiating a new project. What I have in mind is that based on some metadata a github repo should be created with some default data and access rights configured, along with that a default empty pulumi stack as well. Is that something where the pulumi automation api would make sense? Or would you use a dedicated repo with a "standard" pulumi project that did the creation of repositories and other github related stuff based on some meta data? Is it possible to create stacks in this case?
