There's only two places where we're using the C99 feature of array designated initalizers. This feature seemingly wasn't included with C++20 designated initalizers for classes and structs. The only two places we were using this feature are suitably old and isolated that it makes sense to just suppress the warning at the usage sites while discouraging future array designated intializers in new code.
