Bindings: to create or reuse

That said, it’d be pretty convenient if the compiler could pick up some metadata from package.json of installed packages instead of relying on manually syncing these

Honestly, this can actually be done pretty easily in userland; Run a small script on prepare that checks package.json dependencies for anything that matches rescript-* or @*/rescript-* and automatically append it to rescript.json.

Can manually add some exceptions to package.json to include or exclude certain matches. Might take a whack at this for my project
