Typos are kind of funny when you're making a rant about words.
RE: The DS Plans or the Ark of the Covenant as Macguffins/McGuffins/McMuffins/Etcs...
I think it applies here. As FF said, Star Wars (1977) is decidely NOT about the DS plans. The plot may center around the plans, but the story doesn't. The story is about the characters, the galaxy, good vs evil, Jedi Knights and lightsabres, etc...
I had seen Star Wars 100 times before I realized that the plot was all about the DS plans.
And Raiders of the Lost Ark isn't about the Ark... it's about the RAIDERS.
Your point that the wrapping of the plot shouldn't involve the MacGuffin is interesting... but I think it remains a flavour of MacGuffin (egg and sausage) and not the sole definition.
