I agree that there is some risk that it might break some working

be to set all elements to zero using the "= { }" or "= { 0 }"
syntax. Initializers with more elements are, IMO, likely to be
a bug where the user doesn't realize they defined a VLA rather
than an ordinary array. Since VLAs are required to have at least
1 element, would diagnosing initializers with more than one element
more loudly (such as by default or with -Wall as opposed to with
-Wpedantic) be a good solution?
That makes sense to me.
