What is your suggestion?

If the workspace plan step of creating a workspace with the CLI fails with a validation error from terraform, then we should reprompt users for the parameters that failed validation and try again.

Why do you want this feature?

Means that users won't have to restart the workspace create command if their parameters don't pass validation

Are there any workarounds to get this functionality today?

If validation fails, the command exits and they can try again instantly.

Are you interested in submitting a PR for this?
