Do you think it's a good idea to be able to unlock memories from the past?

My childhood memories are blurry in some spots and crystal clear in others. So when I read this article about a subtle "face-swapping illusion" that could bring such memories back into focus, it got me thinking. Which memories would I really want to dig up and see clearly so many years later? Do you think it's a good idea to be able to unlock memories from the past and experience them as if they are happening today? What positive or negative outcomes might result?
