VercelApiHandler should accept VercelResponse as a return type

Idea

The VercelApiHandler function should accept VercelResponse as a return type. because currently i have to send a response and do the return on a separate line to avoid type errors.

now

export type VercelApiHandler = (

  req: VercelRequest,

res: VercelResponse

) => void | Promise<void>;

response.status(200).send(`Hello ${who}!`);
return;

desired

export type VercelApiHandler = (

  req: VercelRequest,

res: VercelResponse

) => void | Promise<void> | VercelResponse;

return response.status(200).send(`Hello ${who}!`);
