The benefit is that it: (a) works in a language without RAII, and C-like languages usually does not have that (b) there are no individual heap allocations and frees (c) allocations are grouped together.

I'm confused: how is it not exactly RAII?
Well, there are no objects, no constructors and no destructors.
*There are no “objects” in the OOP sense, and as such you can say it has “no constructors and no destructors”, but Rust doesn't have “objects” either and neither does it has constructors, yet there's zero doubt Rust is using RAII for memory management (Rust has destructors though, but they aren't generally being used for “memory management” but for broader “resource management”, like network sockets or file descriptors).
If you really don't want to call them objects, there are at least “items” that are “created” and then “deallocated” based on their lexical scope, which is exactly what Rust does too for its RAII.
