I don't think "register types" matter here. The struct module provides
interoperability with low-level *data types* (in C and other common
languages), not CPU *registers*.

So IMHO the question is whether there is an use case for 128-bit
integers; *not* for arrays of four 32-bit integers packed in a 128-bit
register.
