The commits can be reviewed one by one.

  1. The first one introduces { esmodules: "intersect" } to helper-compilation-targets: it can be used to intersect esmodules with the browsers option, rather than overwriting it (fixes The esmodules target should be more future friendly #8809). Note that it cannot be used with @babel/preset-env, and is used by setting esmodules: true in @babel/core. In Babel 8, we'll remove { esmodules: "intersect" } from helper-compilation-target and make it the default behavior for true.
  2. The second one introduces validation and resolution for the new targets, browserslistConfigFile and browserslistEnv option that can be specified in programmatic options and in config files.
  3. The third one passes the resolved targets to presets and plugins.
  4. The fourth one used the new targets in @babel/preset-env.
  5. The fifth commit polyfills api.targets in @babel/helper-plugin-utils, so that we can use it in plugins/presets without worrying about it not being defined.
