I think the interface overall makes sense, but isn't the wording we use
here very specific for hooks?
Taking a step back, what this thing seems to do is to take the hook's
output and customize how exactly we handle this. That isn't really
specific to any kind of "sideband", even though our use case in the hook
code does use this for sidebands.
So maybe we should call this `consume_output_fn` and adapt the rest of
the code accordingly? Because that's what we ultimately do here, IIUC.
