Autopilot Pre-Provisioned Deployment General Availability Date

I'm looking at sue cases for Autopilot pre-provisioned deployment. As per this link (https://learn.microsoft.com/en-us/mem/autopilot/pre-provision) it state sit is still in public preview but it has been there for over 2 years as far as I can see! Out policy is only to use GA features beyond pilot/POC.

Is there a date for pre-provisioned deployment to move to GA? It would add huge benefit to us but as it stands I cannot use it.
