Just wanted to follow up and mention that we merged the first PR for the Automation API Go SDK! https://github.com/pulumi/pulumi/pull/4977
It's in alpha and there will be (mostly additive) breaking changes in the coming weeks. There are complete godocs here that you can check out: https://godoc.org/github.com/pulumi/pulumi/sdk/go/x/auto
In addition, there are still a bunch of holes that we'll be plugging over the next few weeks. Here's a list of known issues that we're tracking: https://github.com/pulumi/pulumi/issues?q=is%3Aissue+is%3Aopen+label%3Aarea%2Fautomation-api
If you'd like to try it out, you'll need to build pulumi/pulumi as there are CLI changes. We'll cut a CLI release early next week that will make it easier to try all of this out. I'll be updating https://github.com/pulumi/pulumi/issues/3901 with instructions and a call for feedback early next week, but I thought I'd let ya'll know in the mean time in case you're eager to kick the tires. If the feedback on the design is positive, we'll follow up with all of the supported pulumi languages.
