I disagree, that area will never be as strong as it was.
Bending aluminum causes strain hardening, which might sound like 'yeah, harder, good stuff' but in reality it becomes more brittle and has a greater susceptibility to crack. Simply put, just regular tensioning of the spoke could pull the nipple through.
If it was a steel rim you could pretty much bang it back into shape and not give it another thought.
