The Panopticon/Old Policy and the Statue of Limitations

So, back in Thread:275976, User:Najawin mentioned the possibility of allowing older decisions to have another discussion after a certain period of time, around five years or such.

I'd support this being implemented, for two reasons.

Updating

Lots of decisions of the older days were made specifically for the wiki at the time, but seem outdated now. Case in point, the thread I mentioned above, where two characters (John Who and Gillian Who) were given one page.

Bias

There was also a lot of bias in the early decisions, even more so than natural. Case in point, the original decision in the thread I cited was due to the characters being considered flat. Now, people can most certainly think that, but I don't think basing decisions off it is good for wiki policy

Conclusion

I'm not saying constant reopenings of issues, but if five years and such have passed, it might be a good idea to allow certain issues that the community feels is outdated to be reaired. It might even allow us to make certain that the decision we make is allowed to breathe and the original drama behind the decision (if there was significant) doesn't affect the outcome.
