We are working with our friends in Windows to add support for some of the settings previously only available via GPO. Once we have these added, we are exploring ways to make this a streamlined experience for admins. I don't have additional details to share now. Also see part of Julia's comment below: "[...]We are planning to support the STIG baseline in Intune eventually, but it’ll be alongside other 3rd party security baselines which are in the backlog, but no concrete timelines that I can share just yet. Right now, our main priority is getting all the existing baselines updated & released before we look at supporting 3rd party baselines."
