While I do like helping, the effort to gain ratio on such a request is not in your favor... If more of the info was centralized it wouldn't be as much as a problem, but from my bit of snooping around I will have to find a command for each plugin to clear information from it.
That is not to say I don't understand why you would make such a request, just that I would prefer to have targets of impactful plugins than 'everything'.
