"Practically impossible" is quite the motivator to a developer.

scribu's first pass at a real post object hit all the right places. One of
the most difficult challenges we face in core deal with backwards
compatibility. Because of this, we've gotten *very* good at writing
forward-thinking code in a backwards compatible way, to the point where the
results are practically works of art. (Code is poetry.)
