Many people open PRs here to add their own implementation of BIP 39 to their “Other Implementations” section. This is fairly noisy, and also places a burden on the BIP’s authors to check those PRs. Some of those links also no longer exist. It just seems like people are adding their links to essentially advertise their projects, and it’s annoying.
Furthermore, it’s not clear to me whether anyone actually reviews the code of those repos. As those repos also tend to not be controlled by the BIP authors, it’s also possible that they may include malicious code after being linked to. I think generally we should avoid linking to code where the authors of the code don’t overlap with the authors of the BIP.
Therefore, I propose that the “Other Implementations” sections of this BIP should be removed.
