It's a feature that other file systems have: why should I choose Btrfs when (e.g.) ZFS can do everything it can and more on top of that?

I remember when Btrfs was announced in 2007 as I was already running Solaris 10 with ZFS in production (and ZFS had non-"experimental" RAID-5-like RAID-Z from day one). Here we are 15+ years later and Btrfs still doesn't have it?

I'm just saying it's not a pitfall, because it's clearly documented up front and warned about. That's orthogonal to whether you should choose this filesystem and why a feature is implemented or not.

The nice thing about btrfs is that you can add/remove drives at will. That allows for easy expansion of an existing pool.

The one thing that ZFS cannot do is defragment a pool.

There are abuse patterns that are toxic for ZFS pools (and all other filesystems). Btrfs appears to be able to repair this damage.
