Probably both. Python ecosystem is expanding super fast. Look what is happening in data-science. Newborn Python libraries getting outdated too soon just like in JS ecosystem.
Expanding? Hope they expand & knock down most of the garbage documentation I've seen in python. I don't need any more library ref static sites like they do with java but with a python feel to them. Give me a functional example of how to use your code, not that you have lots of special methods that do things. Show me how those things are done.
Userguides and references are both important parts of software documentation. A guide that covers problems and their solutions is a good way to start learning how to use a library but when you want to do something that isn't covered by the Userguide you absolutely need a reference that just lists what functions are available on which time in a bare bones manner.
