What changes are you suggesting?
Lots of people are now migrating next.js to OpenNext on workers. However there are a bunch of gotchas. One of them that drove me mad is the fact that env vars have to be duplicated in the Build Vars section when you connect github to deploy.
It would be great if https://developers.cloudflare.com/workers/framework-guides/web-apps/nextjs/ either contained to linked to a page which specifically explained how to configure workers builds with OpenNext. E.g. it should include this support important piece of info: https://opennext.js.org/cloudflare/howtos/env-vars#workers-builds
