- Improves op performance. - Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs per op-encoding (aka: out-of-payload). - Remove shared queue & custom "asyncHandlers", all async values are returned in batches via js_recv_cb. - The op-layer should be thought of as simple function calls with little indirection or translation besides the conceptually straightforward serde_v8 bijections. - Preserve concepts of json/bin/min as semantic groups of their inputs/outputs instead of their op-encoding strategy, preserving these groups will also facilitate partial transitions over to v8 Fast API for the "min" and "bin" groups
