secret methods

[bredele]

It would be able to define routes that are only available through the programmatic API (not HTTP)

service({
  options: {
    get: ['/hellosecet']
  },
  get: {
    '/hello': () => 'hello',
    '/hellosecret': () => 'secret'
  }
})

At any time we could make a method available with HTTP (useful for testing or simply for consistency). Let's try to find an elegant API to enable this feature (maybe through HTTP options - let's remember that the OPTIONS method will be automatically generated from the methods available)
