I mean, the winds are pointing towards pipewire and Wayland being the future of Linux mainstreaming, but there's a reason X.org and pulseaudio are still usually included by default. We're gonna need a few more years to iron out all the issues. Shit, look at something like BTRFS. It's been out for a decade now, and more people still recommend ext4 because it can be buggy in some use cases.
