But don't say "that wouldn't work" when you actually mean "it needs an update". It works on the old Google method, so even if it doesn't follow redirects on other sites, it could easily follow them on Google.

It's not your mom being a bike, it's a bike with flat tires being a bike.

I bet the reason it doesn't do redirects right now is that the situations you find redirects in have usually been places where investigating them loses privacy. But if these were fresh links already personal to your search, checking all the redirects is fully private.
