>you shouldn't be using :has until Firefox implements it, 97.23% of internet users do not care. If you are arguing to not use Working Draft mechanisms in production environments (and you probably are), yes you have a point. Better safe than sorry, it's called a Working Draft for a reason. But if you are arguing to not use something because Firefox (and only Firefox) does not support it, you are going to have a fun time trying to convince most webdevs to care about just 2.77% of all internet users.
