We'd need to look at it in the context of a specific application. As a gap-closure it would be way out ahead of nothing, but with respect to the following structure, a 'wickerbill' could hurt if it caused an overshoot 'jump' situation, especially since it would be in a contracting cross-section, increasing pressure gradient environment. Flow could separate and never re-attach. It's an 'it depends' thing.
