Why doesn't lemmy show communities in the 'all' section unless people from your server are already subscribed to him?

It's excruciatingly obnoxious to have to rely on third party sources for what should be a first-party feature.

Like, I select all and then search a query. "Oh no, nobody on your server used a third party service to find it, so you won't see it here."

Like, how short-sighted is that, really? If I search for a string in the 'all' servers, I should have a list of 'all' the servers containing that string.

It's a really simple concept. Not sure why this post even has to be made, but I'm wondering if there's something I can do to make these 'features' more intuitive.
