It's arguable that a location is the prima facie example of what a context is in GTD - you can only perform actions at a location; it can never be the action itself. Conversely, a project should be a goal and not a physical location (i.e. it should not be a context).

However, Folders can be created to house projects in OmniFocus and these could theoretically have a location context associated with them (e.g. folders for the Office and Home would be representing physical locations). I've not attempted it yet, but can locations be assigned to Folders? Perhaps this is a solution to making OmniFocus less stringent to the GTD mindset and more flexible?
