AAD Group based licensing general availability

What Road Map?

How would anyone even know if the product was getting close to ready without a real plan - a road map - of what it is intended to do and how it is intended to do it? 

The Azure roadmap doesn't seem to list "Group-based licensing" at all. https://azure.microsoft.com/en-us/roadmap/?query=Active+Directory  

EMS Blog last communication seems to be February 22, 2017 Announcing the public preview of Azure AD group-based license management for Office 365 (and more)! https://cloudblogs.microsoft.com/enterprisemobility/2017/02/22/announcing-the-public-preview-of-azure-ad-group-based-license-management-for-office-365-and-more/

The docs don't seem to provide any additional (coming soon) guidelines ... and largely have not been updated since June 2017 with the exception of migration examples (02/2018) and PowerShell examples (04/2018).

Does Microsoft have a real plan for this product or are they planning to start developing base on Preview adoption and user voice comments?
