I think there’s an opportunity here to explain, and get value from, the disconnect between the Clone Wars era Mandalorians who resided in peace on Mandalore, and the Watch / Death Watch tradition which effectively survived through staying in hiding. There’s also the long history of Mandalorians to enjoy here.

Something covering the following points:

The Mandalorians began as warring tribes, forged mighty armour, and mastered great beasts like the mythosaur.
For centuries they warred across the galaxy.
Mandalore became their home, gave them peace and legitimacy - and brought a time when they walked free of armour. Mandalore sustained their race and their people, and became their holy home world.
After the night of a thousand tears and the loss of Mandalore, the surviving Mandalorians turned back to the old ways, with armour and helmets a holy symbol of unity and hope.
Now, they have that unity and hope again, and the removal of their helmets represents the opportunity of their old warlike tradition and the legitimacy and hope to walk free on Mandalore to coexist.
