Can it be implemented without using unsafe?

Do they have in plans to get rid of all unsafe from std?

No on both counts, the entire point of "unsafe" is to form safe abstractions around unprovably safe code.

It can't. And there are many things std does that are in unsafe blocks. There's nothing wrong with that if you have a specific use case for it. (And wrap that functionality in a safe function)
