Not importing Promise.allSettled with useBuiltIns: 'usage'

Bug Report

Current Behavior I’m using Promise.allSettled on source code but core-js/modules/es.promise.all-settled is not being imported on output. Other polyfills like core-js/modules/es.promise and core-js/modules/es.promise.finally are normally imported, the problem seems to be only with allSettled.

Is it because Promise.allSettled() is still a Draft?

Input Code

Promise.allSettled(promises)
  .then(() => {
    // do stuff
  })

Expected behavior/code

import 'core-js/modules/es.promise.all-settled'

Sure, but if you don’t need the rest proposals and the size of the bundle makes sense for you - I don’t recommend to do it, import 'core-js/modules/es.promise.all-settled' could be better -)

You should use something like corejs: '3.5', but now it will not work since built-ins definitions are obsolete on the Babel’s side. For useBuiltIns: 'entry', corejs: '3.5' will fix it.
