D&D 5E (2024) So the Armorer still need be Wearing before Don his armor.

Basically- Iron Man with nano-stuff. So, you put on a suit of plate mail and 'magic' it at 3rd level. Then you can don/doff it at will with a utilize action.

Yeah, this. Specifically later Iron Man suits that expand/contract. I think you could make the case that you're still "wearing" the armor even when it's doffed - as in, it's still on your person somewhere, even if it's all shrunk down into a tight little package.

I guess you would want to take it off if you are drowning or something like sleeping. I have seen and made armor like this and it has never really been a problem. I tend to not make the Pcs into situations where they need to take off their armor or get attacked first thing in the morning when you go to the little boy's room and are by yourself.

LOL. I did that once ... in the Tomb of Annihilation campaign. I wanted to demonstrate to the PCs the "you can't regain lost max HP drain" effect of the death curse, so I had a wight attack one of the PCs while he was taking a piss.

You can't gain the benefit to put on the armor unless you are already wearing the armor.

OP is correct. It's an error.

Some of these errors that have come been discussed lately feel like find-and-replace type errors.

They cared more about the utterly-pointless "capitalize-U Utilize action" than actually making the rules and game better.

That was a oversight in the 2014 rules and is kept. Dumb but the intend is clear in that case.
