There is a bandwidth/latency trade-off here, high bandwidth high latency wants
the whole document in one request, low bandwidth low latency you want to get
the small pieces you need. The high/low and low/high cases it is not clear
which is better. The various link technologies, caches and so on mean that all
combinations are possible and so there is no one-size-fits-all solution.

If hierarchical documents were linearized breadth-first rather than
depth-first you would get the overview before the detail. Anchors that expand
inline would get close to this, especially if backed up by some smart cacheing
and pre-fetching system. The trouble is that you get into some unpleasant
problems with partial documents taken out of context.
