#35864

My PR should probably be superseded by this one, because:

1. @sokra is not only a member of the Next.js core team but also a maintainer of the Webpack.
2. This PR also introduces changes to HMR (which is related to the webpack upgrade).
3. Removal of optional chaining transpilation can be done in a separate PR.

Oh sorry I wasn't aware that there is already a PR for that.

This PR also introduces changes to HMR (which is related to the webpack upgrade).

Actually it's only the webpack update, without any additional changes.

The changes in this PR are only caused by the precompilation step in next.js
