The main win here is abstracting away browser context lifecycle management. Anyone who has run Puppeteer on Workers knows the pain of handling cold starts, context reuse, and timeout cascading across navigation steps. Having crawl() bundle render-then-extract into one call covers maybe 80% of scraping use cases. The remaining 20% where you need request interception or pre-render script injection still needs the full Browser Rendering API, but for pulling structured data from public pages this is a big simplification over managing session state yourself.
