watchOptions doesn't work

[Elrinth]

What problem does this feature solve?

I'd like to ignore a folder which I create folders and images inside whenever I create a product. I don't want the whole website to reload because of that whenever I'm developing... Therefore I wish watchOptions with ignore worked. Like webpack!
Here's maybe something related? #2725

What does the proposed API look like?

module.exports = {
//...
watchOptions: {
ignored: ['/files//*.js', '**/node_modules'],
},
};

Currently it complains like this:
INFO Starting development server...
ERROR ValidationError: Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.

I noticed the same thing and it has blocked me from upgrading to Vue CLI 5/Webpack 5. I doubt this is ever going to be fixed though. This whole CLI tool has been abandoned in favor of Vite.
