Removing outdated rulings?

With the current setup of the complete rulings list being maintained here, but LSJ responding on BGG, what is the correct way of removing outdated rulings?

The current example I'm interested in is the Zip Gun ruling from 2005, which was based on the old card text, and in the this thread , after the text was changed, LSJ contradicts the ruling, (although it's not noted as an explicit reversal).

Always use the most recent ruling from LSJ - in this case: if ZG is destroyed with first strike (and was used to maneuver), the bearer doesn't take 1 damage from ZG.
If in doubt, ask him (on BGG).

I'm compiling the rulings he gave on the NG, but, frankly, Z being the last letter, there's going to be some time before I get there..
