Workflow settings, Workflow deletion

Is there a feature on the roadmap (e.g., under Workflow settings > Workflow publishing) that would allow specific roles or groups to have permission to delete a workflow?

Background: In our current support structure, workflow stewardship falls on citizen developers and workflow owners within the business. They proactively manage day-to-day troubleshooting, receive failure alerts, and escalate issues to IT if necessary. Currently, users with workflow owner permissions can delete workflows. However, until Nintex introduces a proper backup and restore feature, we cannot fully hand over management of our 400+ workflows to the business side. The risk of accidental deletion or, in the worst-case scenario, a compromised account resulting in malicious deletion, makes it critical to restrict the ability to delete workflows to certain user groups. This feature would be extremely beneficial.
