Yea. But for the work most developers do, making their content accessible is largely just learning how to do it. UI toolkits will generally do the right thing out box. Using the semantically correct elements for your content, once you learn how to do so, is no extra development cost. For me, I belive it is the morally correct thing thing to do, for the 1 of me to spend a few hours learning in order to make N people's lives that little bit easier in the future. The main accessibility cost is when it comes to building new UI patterns. But that's a relatively rare case, most sites will be served fine by piecing together elements from existing toolkits and modules.
