Many modules labeled as esm can be loaded by `require()` (prior to `require(esm)`)
When I was testing out https://github.com/nodejs/node/pull/55085/, to get a sense of what modules couldn't be loaded before require(esm) is supported but could be loaded after it's unflagged, I have this script to test loading some high-impact packages locally using require(), and it seems out of 662 packages labeled as esm, 103 could already be loaded by require() even without require(esm), so they are probably dual.
Here is the list I've found:
