Yeah, it's great! Even if you don't get deeply into it, the ability to take and send snapshots, the intelligent caching layer, and the data integrity stuff is all super useful. It's the same stuff that BTRFS sells but it actually, you know, works without constant intervention and data loss. And Zed is great, it ties the whole snapshot thing into the software update process and so on. It's definitely a bit heavier than other filesystems but it's one of those things where I can't imagine setting up a Linux/Unix system without it anymore. I wouldn't exactly classify ZFS as a "new" feature though. ZFS dates to 2004, OpenZFS dates to 2006, and OpenSolaris dates to 2010. 20 years is pretty well into "mature technology" by most standards, even 16 years is very mature by software standards.
