Have you been using Azure AD Group based licensing? What's your recommendation?

Has anyone out there been using AAD Group Based Licensing in production environment? We have been waiting for this feature to go GA but hasn't found any timeline as to when that may happen. This feature has been in public preview for well over a year, really disappointed with Microsoft on this one.

We are considering whether to take a leap of faith and implement it for our production tenant. We would have to do some convincing to senior management as to why this is a good idea.

Any feedback from professionals out there who have been using this feature will be really helpful.
