I think they'd be unmaintainable if merged. Each one is complicated
enough as-is, and they have different concerns and different use-cases
to optimize for. Moreover it's not clear that merging them would buy us
much --- saving one copy step doesn't excite me, even if it actually
came out to be true which I'm unconvinced about.
