Any configuration process is always bound to "unnecessary 
instantiation", if you instantiate
things only when needed then you have to pay a lot of intention to what 
properties are available at what time.

A DSL for lazy operations has proven itself quite valuable as you can 
see from the various tweening apis
they may be a little wasteful but ultimately result in more stable, 
flexible systems that are easier to read.
