I would say disclosing it is good, listing it as a weakness is bad. I did manager training for my job and was asked what my weaknesses are. I said my anxiety and my stutter. Ever since then it has been thrown in my face. Any time something isn't done correctly or there is a miscommunication I'm asked if it was due to my anxiety or stutter. It never is, but there's this constant feeling of everyone waiting for me to slip up. I've realized over time that stuttering is not inherently a weakness. I always had the notion that I was a bad communicator because of it, but that's just not true. I have met a lot of extremely well spoken people that are awful communicators.
