I kinda like the idea of having a black box that stays in the system where you exploded. You could choose to go back and get it or even bargain for someone else to retrieve it on the way back. I really like the idea of stumbling across another explorer's data in a WSS in some random system, then trying to track them down to return it. Or possibly listen to the devil on the other shoulder and sell it.
Of course this also sets it up for piracy, which I don't think is necessarily a bad thing. If you're coming back with 50+ million of exploration data, you might want to wing up with some people you trust. That seems like something a station would pay 5% bonus for, as that data could be more valuable than a normal trade commodity. If only it wasn't such a pain to sell...
I voted for "leave it as it stands" but I wouldn't be too upset about an option to drop your exploration data/bounties/etc. in an electronic format that gradually decayed.
