• 440 Login Timeout
• 449 Retry With

nginx

• 495 SSL Certificate Error
• 496 SSL Certificate Required

Note: I got all these from The Wikipedia Page

521 was added with https://github.com/httpcats/http.cat/pull/119/files

Perhaps worth adding a comment in those PRs linking to this issue for reference.

By the way, we should probably just copy 401 into 561, will create a PR for that

There are also upcoming 103 Early hints. Probably useless though.
