Tried moving a monorepo off Node once. The runtime swap was the easy part. What killed us was the 50-odd package.json files with node-specific stuff baked in. Conditional exports, postinstall scripts, engine constraints, pnpm overrides. Bun got this right by just eating all of that as-is. Deno asking you to throw out package.json on day one was basically asking you to rewrite your entire build config before you even got to try it.
