I originally put it there to allow objects to provide hints to the
frontend on how it should display a representation. This is similar
to how the payloads can indicate where it came from.

I also think it could be useful, although it seems a bit excessive to
store metadata for each output. Here is what I propose. We simply
leave it alone until we have an actual use case that will help us
figure out exactly what this should look like. Without a concrete
usage case, it is difficult to know what is needed.
