At small tip please... I have a small dotnet tool that I wrote called "Pulumi Yoyo", to help manage stack hierarchies a little easier. Where is the best place to post the announcement and potentially get some community feedback (this is my first shot at doing this - therefore newbie mode ON). Thanks. https://github.com/johncclayton/pulumi-yoyo

#built-with-pulumi Is this like a FOSS version of "dependent stacks"?

Depedent stacks, that's a new one on me - probably then! 🙂

Pulumi's cloud offers https://www.pulumi.com/docs/pulumi-cloud/deployments/#deployment-triggers

I'd be keen on seeing how people might want to combine the ideas. At this stage we're not using pulumi deployments - most of what we do is via CLI... precisely why I got annoyed at typing so much I suspect.

At a glance, you've taken the local-first approach, where deployments takes the SaaS-first approach. There might be cases where it makes sense to use both in tandem depending on how you've logically broken up your stacks.
