Initializing structs with memset

Question

Why is it a standard in nordic-supplied code to initialize structs with memset like so? An example would be: 
 ble_gatts_char_md_t char_md;
memset(&char_md, 0, sizeof(char_md));
 
 Instead of a cleaner way: 
 ble_gatts_char_md_t char_md = {0};
 
 I understand that using memset also clears padding bits, but don't understand the reason for doing so.

Well there's style, and space. 
 ble_gatts_char_md_t char_md = {};
 
 forces the compiler to emit code to explicitly set each element of the structure to zero when it's created, for large structures that's a fair amount of instructions. memset, which is usually linked in anyway, is just a function call, less code space.
