Exactly. I look at things like this and contrast with what friends like Adam Johnson do[0] with their community contributions. Adam has many Django packages, along with many other non-Django Python packages. Crucially though, they're not forks that reduce the focus of the community, they're contributions that increase what the community can do collectively.
I think it's perfectly fine to have split effort when you have differing views and goals on something. Developing two exact same things with same goal and purpose might not be fruitful, but variety and options don't usually hurt
