That would break upgrade scenarios where lavc is updated while lavf isn't, 
too, right?

Could this extra prefix be signalled via some other avctx field (e.g. only 
having it present if channels > 2), to keep the output of current muxers 
compatible with future lavc? Or is this use case (wavpack in general) 
uncommon enough not to care about that scenario?
