Having hashcat check certain websites for known hashes

[Spork Schivago]

It's a nice idea for an external tool but definitely should not end up in hashcat.

Is it because it'd be dealing with third-party websites or because there's so many different algorithms that hashcat supports that it'd be really hard to maintain?   Site goes down, code has to be changed, or new algorithm gets adapted to hashcat, gotta find a site that collects the hashes, if any do exist?

And on top of that, the bandwidth for the website could be hammered?

Or do you have other ideas as to why it shouldn't end up in hashcat?
