I think if somebody wants to describe themselves as an "ethical hacker", and a conference wants to let people talk about exploits they've found, the minimum bar for disclosure is at least a description of a mitigation that could be taken, and ideally an actual code diff if its an open source project.

There's a bit of street cred for finding a 0day, a bit of glamour about figuring out the puzzle. There's not much for the person who fixes it. I think as an industry it might be worth trying to fix that somehow.
