I wonder if we should also only allow struct as a subtype of binary?
Structs can technically grow with newer kernels (i.e. new members can
be added at the end). So I think for languages like C we will still
need to expose to the user the original length of the attribute.
And binary comes with a length so codgen reuse fits nicely.
Either way - docs need to be updated.
