But we're talking about Boba. And AOTC did us the honor of showing him as a little kid without any armor. I think that did plenty to lessen the "mystique of Boba Fett". I mean, did knowing he was a clone of some randommercenary who was killed pretty quickly by a Jedi do much for Boba's legend? I can't imagine anything from The Mandolorian that would be particularly worse.
