I disagree.

In classes that are supposed to be global helpers/modifiers, it makes absolute sense to use `!important`. For example, if I have the utility class `.u-hidden`, that selector has very low specificity. But if want to be damn sure that anything I put that class on gets hidden. There's no way to use specificity in this case because it's generalized for use on any website.

This is a common pattern seen in most well architected CSS libraries today.

BTW, I am the they you were referring to :)
