Is NetInstall Dead in Future Releases of macOS? A Discussion for Edu IT

Is NetInstall Dead in Future Releases of macOS? In a recent article, ScriptingOSX posted new features in the iMac Pro which verify observations from the MacAdmins community about the future of imaging Macs. This article is important for my Apple IT peeps advising schools and EdTechs.

I still have a big question mark about this recommendation. In our environment…
