Well, T2/Linux mainly started as an all CPUs supporting System Development Environment mostly for embedded systems and firmware. It is basically like Buildroot or Linux From Scratch fully automated and on steroids. Common users include Access Points, Firewalls, Telephone or LTE switches, NAS, virtualization, or having fun on vintage and retro game consoles and of course prosumers on their home servers and workstations. The benefit is that T2 is not a fixed distributions like most of the others, but you can tweak it to your liking, and build it reproducible with low-code highly portable packages, Thus also increasingly getting into macOS and BSD home-brew ;-)
