tbh the situation with Wayland was not too different, and wouldn't have been better. Compared to Wayland, brtfs dodged a bullet. Overhyped, oversold, overcrowdsourced, literally years behind the system it was supposed to "replace" when it was thrown into production. To this day, wayland can't even complete a full desktop session login on my machine.
So, if you ask me, btrfs should *definitively not * have been Wayland! Can you imagine if btrfs had launched on Fedora, and then you formatted your partition as btrfs to install Linux, but the installer could not install into it? "brtfs
reports a writer is not available", says the installer. You go to the forums to ask what's going on, why the brtfs does not work. The devs of brtfs respond with "oh it's just a protocol; everyone who wants to write files into our new partition format have to implement a writer themselves".
