I also think having XO Lite available will make XCP-NG more approachable for less experienced techs. I'll still use XO to manage my XCP-NG servers, but XO Lite will make that initial server rollout and XO install more approachable.
For the home lab crowd it will probably be better for sure. But why mess with xcp-ng at all when they can get a full featured web interface with proxmox?
Which is kind of my point. Why even put the effort into a simplified web interface running in dom0 when XO is the real thing and can be deployed with a one-liner? And it comes in a free version.
For me at this point all this is more of an theoretical question though as we are moving to pure KVM instead. I feel that the world is moving towards automation and away from pretty web UI. And also away from self-hosting and towards services that someone else will be responsible for.
