How to create a Google Cloud project with service management API enabled?

Question

We're deploying our software on behalf (OAuth2) of users on Google Cloud. We've managed to automate most of it, but there's one bit that's missing.

1. Creating the project is done with https://godoc.org/google.golang.org/api/cloudresourcemanager/v1#ProjectsService.Create
2. Enabling the required APIs (compute, storage, etc) is done with google.golang.org/api/servicemanagement/v1#ServicesService.Enable (can't post as full link thanks to the very bright SO limitations)
3. Creating the instance is done with google.golang.org/api/compute/v1#InstancesService.Insert

The missing bit is between step 1 and step 2: in order to make use of the Service Management API to enable the needed APIs, we need the Service Management API itself to be enabled on the project (how ironic). I'm hoping there must be a way to create a project with some APIs enabled from the start, maybe with cloudresourcemanager, or maybe with https://godoc.org/google.golang.org/api/deploymentmanager/v2, but I haven't found it so far.

So, to restate: does anyone know if it's possible (in Go) to create a Google Cloud project with some specific Google Cloud APIs enabled right on/after creation?

Use the Service Usage API: https://cloud.google.com/service-usage/docs/reference/rest/
