This abundance of flexibility puts most of us to shame. It's like a first-world problem. I agree that chancing a stem failure is not worth the risk, even if it's slight. (At least wait until your kids are out of college!

)
As suggested above, a better solution would be a track stem, shorter stack height headset (minimal gain), deeper drop bars. Or you could always stop stretching and start lifting with your back until the excess flexibility issue goes away.
