module: throw on require('./path.mjs');
This is an extremely important part of the ESM implementation
that should have been unflagged as a breaking change in v12.0.0
to allow us to unflag ESM in Node.js 12.x before LTS. Assuming we
can get consensus on this behavior I would argue that this Semver-Major
behavior change could be viewed as a Semver-Patch fix in v12.0.1
