Importantly, this is not to be confused with the popular slab crate, which internally uses the dynamically-sized, heap-allocated Vec. Although both crates provide indexed accesses and map-like features, option-block operates at a lower level.

Beginner question: does it become easier to write datastructures with complex ownership semantics?
For the specific problem your mention with Vec, slab is quite nice.
What are some alternatives?
When comparing option-block and slab you can also consider the following projects:
scapegoat - Safe, fallible, embedded-friendly ordered set/map via a scapegoat tree. Validated against BTreeSet/BTreeMap.
slotmap - Slotmap data structure for Rust
uniffi-slab-example - An example of how to use slab to send opaque types across the uniffi boundary as an id in the slab arena.
