I think this series is ready and I would really like to see it upstream
soon. I wonder, however, if the path to upstream has already been
discussed? It touches various subsystems, so I don't see immediately who
should pick the whole series? Or if parts should go to different
subsystems offering immutable branches? I bring this up because I want
to avoid losing a cycle just because this is unclear...

Happy hacking,
