On the exact page you're on is a link to an issue [0] acknowledging that the CAPTCHA is inaccessible and expressing that they plan to drop it (albeit with no concrete time-frame). I don't at all understand your argument that Codeberg must be slow at replying to emails (the "manual fallback path") because Wikimedia are; these are two completely unrelated entities and I don't see why you would make inferences about one from the other.
