He's correct about the need to have leaky abstractions; in PEAK's 
architectural pattern, the DataManager is currently the designated "leak 
point".

PEAK, however, at this point isn't emphasizing model-as-design so much as 
model-as-code.  So, if you change your domain model in a PEAK app, you're 
changing it at the code level, and a lot of the other issues then go away.

But he's also right that MDA isn't a panacea; it's a tool, and one that's 
useful to have available.
