It's useful. Disclosing a disability during a job search is risky. An employer taking the time to say "I don't care about your disability, apply." might be the difference between someone qualified deciding to apply or not. That fact that discrimination based on a number of factors is illegal for employers in the US doesn't change anything. People break the law, act inappropriately, and damage careers/job prospects all the time. And, unless they do something supernaturally stupid, there won't be any consequences for misconduct. There's no harm in employers throwing "We're an Equal Opportunity Employer, and mean it" into a job post, or putting up an ad on a site like this. It shows that they're at least minimally serious about it.
