In the link they say:

"Words and actions have meaning and impact, even if your intent is not meant to be hurtful or cause harm. And even if the target of your behavior or comments isn’t bothered by them, others in the community may nevertheless feel impacted by it."

This statement and the amendment collide in my eyes. At it's essence the consideration is whether 'simp' could be seen as a trigger word and potentially offend a third party. This would imply it would be similar but albeit less offensive as the n-word. But since the line is not drawn it would just be a landmine. Since no one would still not be able to use it because the intent does not matter (as per quote).
