I wouldn't want a DnD library to magically 'implement' accessibility for me. How would that even work in a one-sizzle-fits-all way? If I'm building a UI that needs both mouse interaction and keyboard interaction, I want to consider and build both those things, not expect all the keyboard stuff to happen automatically because I used a library to manage mouse events.
EDIT there's a bad autocorrect in there but I'm going to leave it
