option that requires slab and uses usize as pointers?

What do you think about a parallel library to this that requires the use of Slab(s) and uses usize as pointers to other nodes?

This eliminates the lifetime pollution when implementing with a Slab/Arena as backing store and makes the top level container much more ergonomic.
