It is more convenient to store any slicing information (so a memory view object could store an arbitrary slice of another object) as offsets, lengths, and skips which can be used to adjust the memory buffer returned by base.
What happens if the base object changes its memory layout in such a way that the stored offsets, lengths and skips are no longer correct for the slice that was requested?
