I think it probably doesn't really matter. Seeing as this wont ever be included in the core, the only time people will use this is if I clean it up and blog/wiki it. That means they will implement it themselves so "guessing" and whatnot is entirely unnecessary.
I'll knock this up in 2010 by which time hopefully I will have recovered enough to think of some smaller implementation of this.
