Correct. So far so good.

However it also made me the package maintainer for Diablo, and retroactively applied that error to existing packages that I never touched, taking away the credit from the people who did the actual hard work. I'm not necessarily arguing for resources to be spent fixing it (if no one cared in 2010 it's way too late now) but surely that isn't working "like it should".

Then someone else came along and uploaded new versions (I didn't mind at all btw, that's not the point) from a different account but without remembering to change the Maintainer field: and the system accepted them just fine and gave me credit for those too :-/

So if one wants to take over a package without the previous maintainer's approval it doesn't seem like much of a problem.
