I don't think request allows for stale right? But if we would were to allow validation without forwarding (like a local check) we could downgrade Vault validation errors to warnings. But since (I think?) stale requests are not allowed here we're probably good as it is.

Nope! The JobValidateRequest rpc embeds a WriteRequest, which has no notion of stale

## Validate Job

This endpoint validates a Nomad job file. The local Nomad agent forwards the
request to a server. In the event a server can't be reached the agent verifies
request to the leader. In the event the leader cannot be reached the agent verifies
the job file locally but skips validating driver configurations.

~> This endpoint accepts a **JSON job file**, not an HCL job file.
