[Zope-dev] zope.location.pickling.PathPersistent and BBB

While wondering about the ITraverser interface being defined by zope.location, we noticed that the zope.location.pickling.PathPersistent class (which is this package's only user of the interface) is decorated with a recent BBB comment, and had been questioned by a XXX comment for some time before that. The class doesn't seem to be used anywhere in Zope, so removing it would rid zope.location of some unused code as well as make it possible to move ITraverser back to zope.traversing where it fits much better conceptionally. What are your opinions on this, does anyone object? -- Thomas
