Code review comment for lp:~lifeless/launchpad/bug-724033

Strange to see the check that "return None" returns None—and good riddance I suppose.

I would still have liked to see a test, especially since the version I originally tried to review had a performance bug and the overall page is not in a shape that can be tested for query counts yet. I know it's arguably not a "new layer" and this is just a refactoring but you're trying to make an important change and you almost made things worse because of untested new code—however small.
