Sharepoint Online - users access without licenses

Is this a permanent soltuion/feature?  Allowing internal users access to SharePoint Online prior to getting their license for SharePoint/OneDrive allows us the chance to focus on OneDrive and O365 portal adoption while continuing the migration of SharePoint sites from On-premise to SharePoint Online at a different pace.  Or will Microsoft at a later date say, sorry, this option is no longer available.  Note: we do have the required SharePoint licenses.
