I want to use mwclient to explore categories. I can get the list of all categories for a page <https://mwclient.readthedocs.io/en/master/reference/page.html#mwclient.page.Page.categories>, but I don't see how to limit that to just non-hidden cats. At the API level <https://www.mediawiki.org/wiki/API:Categories>, this equates to clshow=!hidden, but how to represent that at the mwclient layer? Meta question: is this the right place to ask mwclient questions? :-)
