Honestly I think using quotes for that is probably better, even though + was a bit less typing. You wouldn't believe how many people search for [tar -xvf] and are confused as to why none of their search results contain the string xvf. It's hard to come up with operators that are easy to type and will never collide with their normal meaning in language, and I think quotation marks work much better for that than + did.
