This is after the job is successfully registered, but before its deployment has succeeded (assuming detach = false). I suppose this makes sense, because the resource is a job, not a deployment, but I guess I want to flag that a failing deployment would still show "no changes" on a subsequent apply, right? So in that case, one would need to taint or otherwise destroy and re-apply the job, if the fix for the failing deployment was something other than the job resource config.

That's right, but that's Nomad's behaviour. The goal of the TF provider is to update the job state in Nomad. Once that's complete Nomad is responsible for the deployment. Applying again has not effect the same way as running nomad job run would also not have any effect.
The default behaviour of the Terraform SDK is to copy the plan result into state which could result in partial state updates, where Terraform state is updated, but the actual resource state is not, in case of an error during the apply. This is normally not an issue because resources are expected to undo these changes on state refresh. Any partial update is reconciled with the actual resource state. But due to #1, the `nomad_job` resource is not able to properly reconcile on refresh, causing the partial update to prevent further applies unless the configuration is also changed. This commit uses the `d.Partial()` method to signal to Terraform that any state changes should be rolledback in case of an error.
