I use it a lot for personal homelab infrastructure. I find it feels a lot more natural than single process containers for the workloads I use (torrent clients, game servers, plex...). I've unfortunately never used it for production workloads, and likely never will after recent news.

I also find lxc system containers better than OCI style immutable containers for dev environments for my personal projects, and LXD is the best way to manage them AFAIK.
