Review comment:
Thinking about it, I am not sure we want this: this will have severe
implications to almost all uses of `value()`. Could you run the benches before
and after this PR?
My suggestion is that we mark this method as `unsafe`, so that it is clear
that people need to be conscious about it. Since this will impact a large part
of our code base (and likely others), I suggest that we do this change on a
separate PR
