For something as LibreOffice I think it absolutely makes sense. The most frustrating thing when working with such software is a crash when you haven't saved your work. Auto-save may help, but it's still annoying.
What this gives you is a reliable way to reproduce obscure input scenarios that trigger a crash, which is often the only thing that's missing for fixing long-tail crashes. Of course, if there were now hundreds of such crashes you'd need to start triaging to avoid devoting hours of bug fixing to crashes no one has ever seen or will ever see, but if it's just a dozen rare ones and one high-profile frequent one ... I wouldn't think about triaging yet.
