does unified@10 intentionally disallow Promise<void> as plugin return type?

[stefanprobst]

it looks like the new unified version enforces Promise<undefined> vs Promise<void> as async plugin return type - just wanted to ask if this is intentional?

import {unified} from 'unified'

const processor = unified().use(() => {
  return transformer
  async function transformer() {
    // noop
    return undefined // <-- required
  }
})

Good catch. Landed: 591b0c0. And released!
