Well, I don't want to remove it just yet, but it's going to be deprecated. Also, after Johannes' remark I thought it wouldn't be a good idea to export the bare test levels to the user. For this reason I reworked the patches to use strings instead of numbers for the test setting (the attribute is now called "pm_test" and is used in a similar way to "disk"). I'll post the reworked series as soon as I update the changelogs and docs.
