Create a new wiki page in new, horrible "experience" UI

In the new, horrible "experience" UI, when I navigate to a wiki library:

../Wiki/Forms/AllPages.aspx

There is NO option to add a new page. When I choose "Add a page" from the "gear icon", it starts a new site page, not a wiki page.

Why is there no option to start a new wiki page?
