CommonJS modules (and anybody else that prefers or needs "require-in-the-middle") can already import ESM. They need to use `await import()` or `import().then()` if they prefer callback waterfalls to async/await syntax. That works everywhere in Node today. Sure, it's a pain when upstream switches to ESM that you have to use more Promises, but that the price you pay and it is certainly a lot less work than a full rewrite even for the most brownfield CommonJS library. You don't have to rewrite everything to ESM all at once. (You should want to, but don't have to.)
