Currently the MCS endpoints move the hatnote below the lead paragraph like so:

In web "See also" text should appear below Wikidata description

Talking to @bearND it seems this is pulled out in the Android app anyway so to service both use cases I'd like to see us remove it from the lead section and instead formalise it as a hatnote parameter in the API response

e.g.:

{
  lead: {
    ns: 0, description: "WWE event in 2016", hatnote: '<div>Also known as</div>'
  }
}
