While linked-lists do have some minor benefits, arrays are more idiomatic in C and may provide a more intuitive API. Initially the linked-list approach was more beneficial than it is now, since it allowed custom attributes to be chained to internal linked lists of attributes. However, this was dropped because exposing the internal attribute list in this way created a rather messy user interface that required strictly encoding the attributes with the on-disk tag format. Minor downside, users can no longer introduce custom attributes in different layers (think OS vs app). Minor upside, the code size and stack usage was reduced a bit. Fortunately, this API can always be changed in the future without breaking anything (except maybe API compatibility).
