Add redirect(), error() etc. to the RequestEvent object?

[qwuide]

I think it would be nice if the helpers intended for use within load/actions and similar functions (such as redirect() and error()) were accessible via the RequestEvent object. This would make it easy for newcomers to see what’s at their disposal by simply inspecting the event object. It would also eliminate the need to import them. Moreover, if the standalone helpers were deprecated, this approach would prevent their usage in wrong places.

So instead of this:

import { redirect } from '@sveltejs/kit';

export const actions = {
  default: async () => {
    // Some logic
    redirect(303, '/projects');
  }
};

You would do this:

export const actions = {
  default: async (event) => {
    // Some logic
    event.redirect(303, '/projects');
  }
};

But I think the most potential benefit of such a change would be that those helpers would be aware of the context in which they are invoked, which might make it possible in the future to implement a typesafe redirect function that would work with relative paths?

The only downside I can see with such a change, if the standalone helpers were also deprecated, is that it would no longer allow external functions to invoke them without passing the RequestEvent object to them. However, this is something we already have to do to a certain extent with, for example, cookies, so at least it would make for a more consistent way of handling these things.
