This is called fragmentation. The advent of slop has caused many repos to stop accepting contributions, and people maintaining their own forks. I do it too, diligently maintaining repos because the original maintainers were either too slow for me, unwilling to add my features, or had moved on.

Since code is now cheap I think it is not the end of the world, but it does suck a bit for users, who may want features from multiple forks.
