I hold out some hope that somebody else will get involved in bcachefs and that the new person will be able to resubmit bcachefs to the mainline.

My impression is that many people respect the technology and would be happy to have it back--they just cannot work with Kent.

But that is the reasons this will probably not happen. It does not appear that anybody wants to work with Kent.
