I think it's just intended to bring more like semantic layers that can work on top of multiple data sources. So, and when it you know like someone from a community is asking me, can I use to federation I would say like technically you can try to use it to that extent but you probably need to look at tree as the better feed for you use case. We have some cross over that we still try to understand my take is that, for example, keep shouldn't do that while we have a cross over the entire source with queering overall.
