 If you ask for a sandwich and you get a hot dog or a wrap, you know you're not getting what you asked for.  Everyone calls them hot dogs, not sandwiches, for a reason.  I'm pretty sure this falls in line with "largely considered" things.  I do not know of anyone who calls a hot dog a sandwich, nor a wrap.

			I submit for exhibit B, 
the open-faced sandwich. Traditionally served on a 
single piece of sandwich bread with toppings. Yet still in the sandwich family.
			
		
	 
 I can link you to a lot of things that, by name, are in a [word] family but are actually not a [same word].  A hot dog, for example, is not actually a dog despite it having dog in the name.  A sandwich 
by technicality and definition involves two pieces of bread.  Wikipedia gets trumped by the almighty powers of the dictionary.
