After completing the Vue 3 migration process using the migration build, we are seeing a bunch of esm-bundler warnings in the console. They all seem to be coming from vue.runtime.esm-bundler.js. Does anyone know if these warnings are anything to worry about, or how to get rid of them. Below is an example of the first few errors. We are still using vue/cli so we have the vue.config.js file.

vue.runtime.esm-bundler.js:8317
Feature flag VUE_PROD_HYDRATION_MISMATCH_DETAILS is not explicitly defined. You are running the esm-bundler build of Vue, which expects these compile-time feature flags to be globally injected via the bundler config in order to get better tree-shaking in the production bundle.

For more details, see https://link.vuejs.org/feature-flags

We followed the Vue 3 migration guide
