I was aware that the juggling would potential screw up scores (including my 
own) but proposed it because it was a move in the right direction, meaning that 
I knew we would never be adding these stencils back in again.

I think Harm is right that, irrespective of documentation, users use what's 
available.  If we're going to add something, we want to be sure that it has a 
certain degree of permanency.  I don't think we can treat it as an 
implementation detail if it is publicly useable.
