Yes, this. We need a way to link communities on different servers together. I want a unified feed with tech discussion from beehaw and from lemmy.ml, but right now these are two separate feeds. I also want to sub to "tech on every federated instance" but I can't tell lemmy.ml that "hey, I want all tech news you know about". I have to manually scrape communities and sub to all of them. And that doesn't even help if new ones are created every day.
