The original explicitly initializes the members using designated init, and the loss somewhat feels like a temporary regression, but as long as the new norm is

 - If there is *no* member that is initialized to non-zero value, we
   use { 0 }, and
 - Otherwise, we only explicitly initialize members to non-zero
   value using designated initializers
this conversion is perfectly fine.
