   Providing an array of (pointer,length) wouldn't be too much extra
work for a split vector implementation.

   Yes, although its something you try to avoid.

   I'm not saying that this is an important use-case since no one
seems to have produced a split vector implementation that provides the
buffer protocol. Numeric-style array handling is much more common so
deserves priority.
