Because?

I don't see anything there that's fundamentally changed. Btrfs repair code is still quite weak, and "btrfs ate my data" stories have reduced somewhat, but I'm still seeing them come up, and the core architectural issues haven't changed. Josef was recently saying on lkml that they (the btrfs team, at least at facebook) have accepted that XFS will always be better in many scenarios, and to me that's an admission of failure - a COW filesystem should work just as well as a previous generation non-COW filesystem in nocow mode.

A mission statement like that is fundamentally saying "these are my priorities, this is why we need to do better" and I stand by what I wrote, because taking on writing a new filesystem - the part of the operating system with the highest requirements for "this absolutely has to work" robustness - really is about having the right priorities.

Gotta take your time your time to get things right, make sure the fundamentals are solid, before chasing all the features - this isn't an area where typical silicon valley "go big or go home, fake it till you make it" attitudes can work.

Yes, I rather think that's the point. And this is clearly the point at the party where I find an excuse to move on from the very earnest person who's decided that something is wrong on the internet and say "sure man...good luck with that".

Good luck with that.
