my bad for being unclear: I meant dragonscale mail
As for the taboo, so many things have changed in DnD in the last 50 years: races (you can play a djinii or vampire!), there are no rules about alignments and classes anymore, new classes, new subclasses and feats have been added that give PCs access to spells on the spell lists of other classes, giving Clerics access to all martial weapons, and there's a Wizard subclass that can use a sword (1-handed melee weapon) (Bladesinger), etc. Allowing druids to wear some metal armor does not break the game, given these changes.
IMO the real concern is people who want to make their PCs OP, which there are many ways to do. And there are many ways for DMs to manage this.

Started playing AD&D in the late 70s and stopped in the mid-80s. Started immersing myself into 5e in 2023
