> We need to reincarnate on-stack-upgrade feature in less functionality way. It's true,
that we don't need an analog to Stack Advisor or Upgrade Packs, however we need a way to exclude
some property from being merged with stack defaults during Upgrade.
> Why we need this: there could be a lot of situations, when we need some properties only
in some 
> picante moments, and these properties regulated according to Stack Advisor/Wizards or
another internal state. In this case, these properties shipped with dummy stack default values,
which are incorrect.
