It uses data and/or metadata mirroring on other devices/partitions if you choose so. I can't really comment on the other points, since I'm a user and not a developer of the FS. But why do they matter in every-day circumstances, anyway?

They depend on atomics, data integrity and duplication, and on the FS itself being steeled against its own metadata getting tainted.

btrfs isn't really just about performance, it's about capabilities. btrfs is hugely different from a simple partition format like ext4; btrfs incorporates volume management and redundancy and all sorts of other features that are usually layered on top of simple formats with tools like LVM and mdraid. The capabilities btrfs brings to the table are really useful for distributions, which is why there's always a desire to make it default, but the tools and performance may well need to catch up before this is plausible.
