Property '$options' does not exist on type 'VueConstructor<Vue>'.

Steps to reproduce

import Vue, { PluginFunction } from 'vue';
interface PluginOptions {}

export const Plugin: PluginFunction<PluginOptions> = function Plugin(Vue, PluginOptions): void {
  Vue.mixin({
    created() {
      this.$options.socket = 1;
    }
  });
};

What is expected?

The $option should be already type right.

What is actually happening?

Property '$options' does not exist on type 'VueConstructor<Vue>'.ts(2339)

Is there a reason that some public members of the Vue class are not included in the type definition? This is getting really messy for me as I'm having to create a vue-shim.d.ts that augments the VueConstructor type as a work around for this issue.
