Summary: Changelog: [General][Removed] Remove experimental support for loading bytecode from Metro Removes the experimental bundling strategy that offloads Hermes bytecode compilation to the packager server. The React Native parts of this experiment were never part of the public API, and the Metro parts never fully shipped in open source. Followup from D43597007.
