Damien Sweeney we don't currently support importing/exporting a baseline across tenants, but it's something we're thinking about. we'll be releasing a view of the settings in the baseline momentarily. it will be part of our core docs, linked in the essentials pane on the baseline itself.
Raymond Huis in 't Veld deployment is supported for any AAD group, including static and dynamic user and device groups
Miguel Sanabia you should have it in all tenants now. if it hasn't popped up in Intune yet, search for "Security baselines" in the top search bar
Deleted you'll see it in Intune shortly, and it is the same option as the root of Azure. it's just taking a bit more time for the Intune menu blade to update. see my answer to Damien above for export.
