This was what I was thinking. I was basing that on the idea that `= { 0 }` to zero init the entire array is far more common than ` = { 1 }` to init the first element to one and the rest to zero (which is a case I think this diagnostic shines on because some users think that will fill all `1` instead of only the first element).

If there are other patterns, I'd love to know what they are.
