A spatial remapping plugin for output buses would be usefull as well, because Atmos and Auro 3D speaker placements are fully incompatible.
At least this would give the possibility to mix for Auro 3D and Atmos using the same room.
Only largest studios have the financial capability to build different theaters for each format or to build a dual speaker setup arrangement in the same room.
See here for a description of the Atmos / Auro 3D compatibility problems, and a remapping solution offered by Trinnov.
And an interesting video explaining differences between Atmos and Auro 3D.
