Are any of the runtimes already implementing this?

Features in 3.0 presumably also being mostly implemented already, some maybe just kept behind feature flags.
Wasm 2.0 is complete in a handful of engines, whereas 3.0 is less well-supported.
Wizard is almost done with 3.0; only memory64 and relaxed-simd are incomplete.
