Not only is this an experimental API, but also because the RngBitGenerator is not guaranteed to be stable across compiler versions (or backends or shardings), let's assert that this JAX PRNG implementation may not be stable across JAX versions. Even without that kind of stability, this PRNG is still useful because compared to effectful RNG primitives, like lax.rng_uniform, this RBG PRNG will still work correctly with lax.scan and jax.checkpoint (while still potentially being more performant on some platforms than JAX's standard PRNG).
