Interesting, I have not looked at the Vue CLI code in some time. What about users on older versions of Vue CLI? Will they have a problem?
We have tests around this https://github.com/cypress-io/cypress/tree/develop/system-tests/projects/vuecli4-vue2 Vue CLI 4 and Vue 2. Amazingly they are all passing - but I don't understand how this can be the case, unless
service/lib/Servicehas always been a thing?There was a problem hiding this comment.

Well, the v3 branch of vue-cli contains the file and to me it does not seem like much of the called code has changed.
I think #23605 would allow to move the fix to vue-cli code (e.g. return a promise from their
webpack.config.js), but the main aim of this pull request is to get the default configuration to work with avue.config.jsand"type": "module"and I do not know if there are other conflicts on the vue-cli side.
