So, are we agreeing that btrfs isn't fit for purpose, then?

Kent, whenever you're at a point where you could make a good decision and make progress on any non-technical axis, you choose to attack something or someone. This is why you're getting the reactions you are getting. bcachefs design looks good, literally everything else about the project is miserable, because of this.

Now, I fully expect you to react poorly to this message, too. That is the expectation the world has formed of you. Think about that.

I don't understand your question. Are you going somewhere with this?
