If it happens live, on the server where a problem was observed, then it dodges the whole bureaucratic hell problem, and puts a hacky patch up immediately.
It's not a real fix, of course, it's just a dodge for an observed, live vulnerability. At least maybe your computer won't be a botnet node in the meantime, if you're alert enough to notice the takeover, nor will your website be down.
Maybe you can even get it to generate some input based on your vulnerability, to more easily reproduce your problem, and a hint that links to the symbol file so you can see where it went wrong. If that's possible, you'd give half the problems a potentially quicker trip through the verification queue/trouble ticket queue/triage system, plus you'd cut out most arguments about how it's not reproducible.
Sounds fairly promising to me, though of course it'll probably have its own problems. But hey, so does GDB, and yet it still helps make certain problems quicker and easier to nail down.
