Following up on the previous update, if a workload (such as Planner) is enabled for Outlook by default, we don’t plan on hiding those groups from the GAL. The only other scenario currently under consideration where we would hide groups by default is “Secret Groups”. “Secret Groups” would be hidden from everywhere unless you are a member. “Secret groups” is on the Microsoft 365 Groups backlog, but there is no delivery date available at this time.

Can't believe this isn't fixed yet as it seems like the most basic of functions. Why the #"$! would we want a bunch of random groups cluttering up the address book? I'm trying to find ways to disable Planner, Teams and SharePoint to avoid this problem altogether.
