+1 to dropping the columns.

As far as breaking reports, we would need a good release notes entry giving people a heads up about the potential problem before the upgrade to a release with this code. However, I'm hoping there aren't many reports out there that would be impacted by the change. I don't know many libraries that would be likely to report on those fields. If the concern regarding reports is very strong, I would be in favor of a message to the general list as Rogan suggested.
