@gabby325 Sorry for the late reply. Since my notifications lately are mostly vote and added into collection, I must have missed the conversation notification.
I'm somewhat 50/50, on one hand, the psycoframe can be a great way to solve any misunderstanding and conflicts if used correctly, but after what it has shown in Unicorn OVA and Narrative movie, psycoframe is basically a Deus Ex Machina.
If used in wrong way, one Newtype can be a living WMD, so I think it's reasonable too to seal the technology away.
Plus, it somewhat explains why future UC Gundams like F91, Crossbones, and Victory lack the feat of what Nu Gundam and Unicorn Gundam did.
And while it's not canon, apparently in SRW30 lore, Nu Gundam counts as Majin: Machines with capability to wrap reality and time and basically put Nu Gundam on the same level as Super Robots like Mazinger, Shin Getter, despite being a real robot.
