Should we expose separate methods on default export?

[tunnckoCore]

Like that

const dush = () => {
  // ... code
}

const app = dush()
app.dush = dush

export default app

so we can just

const { on, off, once, emit, use } = require('dush')

or get the singleton

const { dush } = require('dush')

Actually... why? Don see fit for this, so it won't land until anyone want it. Ping me if you want to do it.

edit: I'll leave that open for feedback.
