They're currently in a private repo, only because they use an old crusty implementation of the graph DSL. We're porting them over to the open-source graph DSL (tree-sitter/tree-sitter-graph), and we'll add them to the tree-sitter-python repo as part of that effort. As mentioned above, future language development will happen directly in the per-language tree-sitter repos using the open-source graph DSL implementation.
