Flexibility you don't need is memory bandwidth you don't have to
spend.  We're pushing close enough to the limitations of the
hardware, it's a real concern.

The server code that deals with this data doesn't know if the
properties it is accessing are coming from the template or the
instance.  It's transparent to it either way.  The only code that
has to change are the parts that control reading and saving the
character data.
