Type-narrowing subscription key

[oscartbeaumont]

Idk, if I will do this but it might be a good idea.

Eg. current code:

useLibrarySubscription(['jobs.progress', activeJobId as string], {
  onData: setRealtimeUpdate,
  enabled: !!activeJobId && !showChildJobs
});

Making something like this work:

useLibrarySubscription(() => !!activeJobId && !showChildJobs ? undefined : ['jobs.progress', activeJobId], {
  onData: setRealtimeUpdate,
});
