Since when? It has the best CI, has the best interface, has both Hg and git support, and does pretty much everything a forge is supposed to do. It also does discovery better than any other platform.
I disagree with the rest of your comment, but the rest is wrong enough and obviously in bad faith enough that a response would be unnecessary.
So I went to https://git.sr.ht/ which shows me nothing but buttons for login and register. Same for https://sr.ht/. I'm really confused if I'm holding something wrong, but this doesn't look like discoverability at all. Is it better if I create an account?
This is the easiest possible interface for discovery of projects, which is (in my opinion) something that GitLab and GitHub are pretty dreadful at. I'd go as far as to say there hasn't been a forge good at it since two SourceForge redesigns ago.
Reminds me of the kind of comments I unlocked when I took donations for my forum and someone who gave me $10 once, a year ago, would write paragraphs about how I'm misallocating their money.
