Certainly the idea of a public bug database is not anathema to us, but it's difficult to transition towards (going from a private database), and can add a bunch of concerns about what you can and cannot write on it. Not all of our code is public and most of our code is by internal employees not volunteers, so the benefits likely would not be huge at the present time.

All that being said, I wouldn't rule it out.
