Can I find (the old) excerpt/Wiki of a tag that is now a synonym of another tag?
E.g. the excerpt and Wiki of the arima tag builds on ARMA (does not discuss what ARMA is). But since arma has been made a synonym of arima, the excerpt and Wiki of arima now would need an update to explain what ARMA is. I wanted to borrow these from the arma tag, but I do not know how to access its (old) excerpt and Wiki now that the tag no longer exists independently.
