Ask HN: Is JIRA Kanban Really Kanban?

I just read a whole bunch of Kanban and Scrumban books (Anderson, Ladas, etc.). And then I load up JIRA to see how to use it with Kanban and I only have columns corresponding to these generic statuses?

Isn't that completely missing the point of Kanban with visualizing the value stream? What do other teams do? What are alternatives for real Kanban visualization of the value stream?

Am really curious what other teams have used for this (esp. organizations where some teams might be using Scrum and some might be using Kanban).
