> 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.
