I think we still like the Brits, so you should be safe there. As long as we don't go to war with Brazil or England, you should be fine.
Seriously, I think this could be an interesting topic. One never really knows what is in the minds of SLS/YLS, so who knows if it will "help," but I don't see how it would hurt (obviously as long as it is well-written). They ask you to submit an application that tells about you as a "whole person" or whatever, and they claim to evaluate each application "holistically". All you can do (legally) is give them what they ask for.
