All this mess is because someone noticed that the poorly-described checkbox says "Hide action" but the API was still reporting that the subtype (here named 'action') is "delete" (versus "restore", "revision", etc).
I don't think action was ever truly hidden in the UI; obscured at best. The <li> elements for the log items still get an mw-logline-<action> class even if the action is suppressed.
