[cometkim]

This is an umbrella issue to track and discusses the remaining issues to be resolved to achieve "Library Mode"

I've written the script to support library mode for rescript-struct. https://github.com/DZakh/rescript-struct/blob/main/packages/prepack/src/Prepack.res I'll share the problems it solves a little bit later when I have time.

Following! The above two issues would prevent the need for a secondary build step (rollup) and make making libraries much simpler.
