Allow ws proxy rewrites in next.config.js

[PullStackPigDev]

Today I was thinking, wouldn't it be amazing if we can have ws protocol destinations in config?
Since vercel serverless functions have a timeout pool, it does not allow real-time communication.
I have a place where I can host a ws server but cross-origin is really annoying to deal with, it disallows some parts of my auth implementations.
If we can allow this

async rewrites() {
  return [
    {
      source: "/ws",
      destination: "wss://example.com"
  ]
}

Then I believe more people will use vercel!
What do you guys think?
