Which, let’s face it, is dumb. Other clients should be able to recognize linked Lemmy instances and handle the click transparently.
Instead, now we have links that can’t be shared outside of Lemmy and links that should only be shared outside of Lemmy.
Every Lemmy instance can see which other fediverse instances they’re connected to, I’d be satisfied if it scoped to those instance domains. It’s going to be very rare to have a link to a Lemmy/kbin/whatever instance that is not already being followed by one local user, and when it does happen, the first time any local user follows it, it’s fixed again. That covers the 99% of cases better than having to educate every user every time in every thread they innocently post a normal url instead of knowing how to even copy this special url from.
