Apply default quota
Now Office 365 Groups have the way to apply the quota against "existing" Groups via Set-SPOSite PowerShell commandlet.
IT admins expect to be able to apply the default quota which means every new Groups use this quota after apply this value by IT admins.

Is the tenant property OneDriveStorageQuota tied to the group default quota for groups? If so, can we have a separate property that governs groups over OneDrive For Business?
