   Currently, as alluded to @bjchambers, the length of a `Buffer` is somewhat immaterial, with length solely a property of the Array / ArrayData, and the size of the underlying buffers kind of arbitrary. This is in fact key to how ArrayData and Array slicing currently works - it doesn't actually slice the underlying `Buffer` at all.
   
   There are suggestions to change aspects of this, e.g. @jhorstmann on https://github.com/apache/arrow-rs/pull/1499, but I'm not sure where they've gotten. I personally need a better idea of where we're headed w.r.t buffer offset handling before I'd want to weigh in on what we should do here.
