I think also that some fans are transferring their wishes for Boba never removing his helmet along with Din Djarin to declare that they should have never removed the latter's helmet. In the old EU this was not a thing at all. In the Republic Commando novels, they removed their helmets whenever they weren't in danger. They would sometimes use their helmets when around outsides for the intimidation factor, but just having the armor on does that job.
My gripe with the armor, and I did like his original armor, is that now they seem to think that if you have Beskar, it's shiny like his armor. Beskar can be painted (colored?). Well in the EU, but hopefully in canon. I really dug the idea from the RC novels that you might wear armor components from your deceased relatives to honor them so you might have mismatched pieces. One character from those books, 40 years later, wears parts from all his uncles so his armor is all kinds of colors, but the sentiment is pretty cool, IMO.
