I was talking specifically about the practice of mass-closing bugs due to the release of a new GNOME version, without any particular reason to believe that the specific bug has gone away.
I don't see anything wrong with requesting more information on a specific bug and closing it if the reporter doesn't provide that information. I just object to having to babysit a pile of bugs and mechanically reopen them each time someone mechanically closes them.
Valid reasons to close a bug: "can't reproduce that in the current version", or "the entire subsystem you reported the bug against doesn't exist anymore in the current version, and its replacement doesn't have that problem". Invalid reasons to close a bug: "there's a new version and we don't care about the old one anymore", without actually testing that the new version doesn't have the problem, especially when it turns out that it *does*.
