You're right that if we do find something that makes it irrelevant, it won't be needed. Let's not make perfect the enemy of good here though - it's a mild preventative that actually may help someone at risk. There have been studies that show that even _reporting_ on suicide can cause an uptick of rates without the proper precautions. If it doesn't impact you, great. If it helps pull someone else off the edge though, it's worth it.
