Why not?

Why not simply change composite tvbuffs so you can add stuff in
arbitrary places and have holes?

Attempts to fetch data from holes would throw a new exception type. 
(Note that a "hole" due to, for example, a tvbuff having a length
shorter than its reported length would cause a BoundsError exception to
be thrown, not a new type of exception.)
