Oh, interesting! I still haven't played with bcachefs, so I didn't know you can do erasure coding replicas there. Although they says the implementation is still simple so it suffers from "write hole".

That's what I was hoping Kent would show up and expand on. His March 29 update[0] says that erasure coding "has seen a lot of progress" which makes me hopeful.
Maybe, if we're lucky, Kent Overstreet (koverstreet[3]) will magically appear and talk more on his latest creation.
