This is all amazing. But I think its missing discussion that the deciding factor of a sandwich is not the filling - in this case hotdog - but the nature of the casing. Merriam-Webster’s definition for sandwich: “two or more slices of bread or a split roll having a filling in between.” is soooooooo wrong because a roll is a roll; a filled roll; a roll and sausage (not a sausage roll - that's a totally different beast that involves pastry). The filling needs to be encased in a bread type covers that need to have been cut from a larger whole ie a loaf of bread, a large ciabatta or foccaccia. It's the fact that there is bread left over - potentially to make ANOTHER sandwich - is what makes it a sandwich. Thus a sub is not a sandwich.
