Yes, it's a bit frustrating, especially for headers with inline/macro code. And for headers, requiring C23 doesn't seem sensible for quite some time. I define a macro:

    #ifdef __cplusplus
    # define ZERO_INIT {}
    #else
    # define ZERO_INIT {0}
    #endif

Works for arrays, aggregates, scalars, etc., but I just use it for arrays and aggregates: `char buf[32] = ZERO_INIT; struct X x = ZERO_INIT;`
