I think there some lack of context but geometry nodes is a way to create tools and assets without python at all, providing them as extensions by some creators currently is more like hacking to at least made something.
Every time something is designed in geometry nodes one of the main goal - make it such low level to allow technical artists create whatever they want. The other side of the coin is - there is no button make as _pask class of tasks_-artis want. For instance, you simply can not re-create current built-in instancing feature with geometry nodes in just one click, this have to be designed solution, see Remove legacy instancing.
And if we would able to embed some already existed built-in features into blender (like shade smooth modifier), and in future provide new features via online asset repository, i think its also about solutions provided by users, like other implementations of particle physics of hard-surface modeling node tools (not sure blender would be able to just maintain all of them even as online assets, this is something that should be outsourced and just use blender platform for sharing, communication (maybe also use this in development purpose for automation testing, benchmarking and technical feedback)).
Personally, i just do not see any difference between python and blend files as something to share, but i would prefer blend files with just a things over then a some script.
