I have one particular project I do for work and when I'm ready to sit down with that project I work out of a focused Project Mode with the Inbox in view. There are often many items that have accumulated in the inbox that need to be brought into the project. While working on that particular project on my laptop it is very helpful to see the future items and all the various contexts like Waiting For... at the same time. Clearing the inbox, reviewing the project, and acting on remaining actions can all be done in one sitting and in any order that seems convenient at the time. Of course I could not use Omni focus on the iOS in this way but in this particular case that is not a problem because this project requires the use of several applications that run on the laptop OS. Historically (yes, I've been using this app along time) I came to this method of working because I could see the inbox at the same time. If I did this the traditional way, by clearing the inbox first, I would still have to move the actions around among the action groups within the project itself before changing the focused view from Project to Context and this method saves me some of that tedium.
This is the only time I use OmniFocus in this way—otherwise I work out of Context mode and do not expect immature actions that are still in the inbox to appear.
