Roman accounts using interpretatio romana (equating Germanic deities with Roman gods) aren't the same as direct written evidence naming "Odin" specifically. The bracteate's significance is that it contains the actual name in runic form, not a Roman interpretation or equivalent.

Sure, but claiming that it pushes back the date of Odin's worship back 150 years is wrong. It hasn't made any change to our beliefs about when Odin was worshiped, or where, or by whom.
