How to recreate apollo queries within a component?

[fnoop]

If I have a query with a default client set within a component:

computed: {
  activeApi () { return this.$store.state.activeApi }
},
apollo: {
    $client () { return this.activeApi },
    vfrHudMessage: {
      query: vfrHudQuery,
      subscribeToMore: {
        document: vfrHudSubscription,
        updateQuery: (previousResult, { subscriptionData }) => {
          return {
            vfrHudMessage: subscriptionData.data.vfrHudMessage
          }
        }
      },
      mutation: vfrHudMutate
    }
}

If the client changes, vue-apollo ignores that, so I make it react by wrapping the component call with a key, like:

top-nav(:key="activeApi")

Then whenever the activeApi store value is updated, the entire component is destroyed and recreated with the apollo using the new default client. This works fine as a workaround, but it's pretty ugly and inefficient if you have large components which take a long time to destroy and recreate.
Is there a way to just destroy and recreate the apollo queries within the component? Ideally it would react to the $client value but it doesn't, but if I could at least refresh the apollo queries without destroying the entire component, that would be a much better workaround.
