   > Basically, the `ArrowArrayView` doesn't care how the memory it's pointing 
to got there (i.e., there's no requirement that an `ArrowArray` ever existed). 
This is mostly helpful for reading IPC: the decoder first fills in an 
ArrowArrayView and only allocates the `ArrowArray` if requested.
   
   OK, understood! I see the C doc comment actually mentions this: *"use it to 
represent a hypothetical ArrowArray that does not exist yet, or use it to 
validate the buffers of a future ArrowArray."*.
