   - Proposal: [“Entry Points Proposal”](https://github.com/geoffreybooth/node-esm-entry-points-proposal) covers non-file forms of input as well as adding `--type` flag for controlling file-based input.

 ### Needs Consensus
 
-* Determine the name and functionality behind command-line flag(s) for specifying CommonJS or ESM.
-  - See https://github.com/nodejs/modules/issues/300.
-  - Apply to non-file inputs only? Entry point only? Package scope/mirror `package.json` `"type"`?
-
 * Finalize support for (or removal of) `import` of CommonJS files and packages.
   - See https://github.com/nodejs/modules/issues/264.
   - Defaults only or named exports? Behind a flag or not?
+
+* Provide a way to make ESM the default instead of CommonJS.
