Getting web (and webpack) working with previous Expo project

Expo SDK
8

This issue is still open : [Web] Previous Expo 36 app `Can't resolve '../Utilities/Platform'` · Issue #73 · expo/web-examples · GitHub
We need a clear process to solve this, otherwise it’s impossible to promote react-native-web as stable enough for projects. I’m stuck since months now, hoping that this would be solved in a reasonable amount of time and effort. But it’s not, more and more developers fall into this trap, please solve this asap.
