Sure. For me, what makes an open source ecosystem healthy is that a high-quality contribution can reasonably be expected to be adopted by a majority of users. This creates a virtuous cycle of Idea → Implementation → Adoption → Refinement.
This cycle requires a critical mass of people to both do the work as well as share the new ideas with the outside world. If your community is too diffuse across multiple, incompatible versions, good ideas will (over time) tend to concentrate in less fragmented communities.
