Env 7 / Node 4 useBuiltIns usage transpiling polyfill call with "import" not "require" #7457
Description
Here's my config:
{
"babel": {
"presets": [
[
"@babel/preset-env",
{
"targets": {
"node": "4.0.0"
},
"useBuiltIns": "usage",
"debug": true,
"shippedProposals": true
}
]
]
}
"devDependencies": {
"npm-run-all": "^4.1.2",
"@babel/cli": "^7.0.0-beta.40",
"@babel/core": "^7.0.0-beta.40",
"@babel/preset-env": "^7.0.0-beta.40",
"babel-core": "^7.0.0-bridge.0",
"babel-jest": "^22.4.1",
"jest": "^22.4.2"
}
}
Here's debug output:

Using polyfills with `usage` option:
{

}

Using polyfills with `usage` option:
[./functionality/bin/index.js] Based on your code and targets, none were added.
[./functionality/index.js] Added following polyfills:
es7.array.includes { "node":"4" }
regenerator-runtime { "node":"4" }
es6.promise { "node":"4" }
Why on earth does my index.build.js file have an import statment?
./functionality/index.js
import "core-js/modules/es6.promise";
require("regenerator-runtime/runtime");
require("core-js/modules/es7.array.includes");
