Jiachi Liu 0e6e83c33d Add warn and telemetry for customized esmExternals (#67339) ... ### What * Warn with next.js when users customized `experimental.esmExternals` value * Add telemetry tracking on the customization usage for that flag. 0 for no customization, 1 for used non-default customized value ### Why `esmExternals` ideally can just remain as default value `true` which Next.js can handle the customization properly. Since next.js app router also supports it on canary now we're adding a warning to users that don't modify `esmExternals` option as it could affect module resolution on ESM packages.		2024-07-01 18:28:11 +02:00
