Yeah, but in some cases (eg. mine!) this just isn't possible.  I 
personally would love to see something like what Doug proposed 
implemented.  I already have a couple hacks in my code to do something 
like this in a couple extreme situations with help from the lifecycle 
interface...

As for it being model intrusive, I don't see a problem with being a 
little model intrusive to support a use-case that you do not recommend 
(ie. not using generated identifiers).

Just got back from vacation and I can't wait to test out the new 
normalized table mapping functionality.

Thanks,
