Thanks for the answers, this sort of answers my question on the practical value for personal use. Att the moment when home users want to go into dodging browsing they can switch to Edge using sand-boxing and virtualization.
The whitelist has value for corporate users, they could automatically switch to virtualization when using their PC to visit not-whitelisted corporate websites. But it is offering ' mustard after the meal' as we say in Dutch, meaning that most large companies already have policies in place to deal with risky PC usage.
At the moment, most large companies in the Netherlands have a clause in their labor agreement in which they promise to use their company PC in a wise and respectful way in compliance with the norms and values of that large company. Many labor agreements of large companies contain the clause that you will be fired when you don't comply with these conditions.
So also for corporate use it has limited value in the Netherlands is my guess (maybe only critical infrastructure companies and governmental bodies).
