X-omnifocus-debug Settings in OmniFocus 2 and iOS 8?

In the past, I’ve used the x-omnifocus-debug settings to speed up my sync performance, but somewhere along the way they seem to have gotten reset back to their default values, and now with iOS 8 I don’t seem to be able to use them anymore. When I enter a setting directly into Safari such as:


Safari basically now treats that as a search, thanks to the new omnibox, I suppose.

If I format it thusly:


OmniFocus opens, but then tells me that the command isn’t valid.

Is there some other formatting I should be using, or have these commands been changed internally in more recent versions of OmniFocus?
