See my answer to Stefan in the same thread. I am absolutely convinced that this 
would be a nonsense-parameter which increases complexity at no added value.

Let me know if you're able to construct a scenario which cannot be solved in 
current resolve order and is sufficiently common to require resolving it. 
Moreover such a switch would apply to all packages, so admins would have to 
decide from the beginning which approach to use.

Also think about the fact that during operations inside WPKG which do not 
involve package (e.g. evaluating profiles or evaluating packages applying to 
profile) the order is now also clearly defined (host override profile). Just to 
mention it before somebody brings up the idea to make it even more complex by 
adding that switch on package level which would then introduce inconsistency as 
well (variables evaluated differently when used in profile than using it within 
package). The results would be extremely difficult to predict even for me - and 
I guess almost impossible to predict for the average user. Not even to mention 
the tremendous effort of additional test cases required.

Feel free to convince me and provide examples where a switch would be the only 
way to handle it.
