Summary

Looking over the RN codebase I've found that ReactNativePrivateInitializeCore reexports InitializeCore. Inside commit history we can find attempts at making this module a noop but ultimately it was always reverted because of issues at metro.

We're not using metro and this isn't an issue with webpack/rspack so no reason why not to try it, especially since this allows for inlining entrypoints for faster startup (before webpack bailed out of this optimization because InitializeCore was used in other places)

Test plan

Any measurable improvements?

measurable? maybe
noticeable? nope - but we would probably need to go to low-end android devices to see the benefit tbh
