Better that than dragging along a zope.app.* dependency into the new
package, whose purpose in life is to make generations useful without
requiring any of zope.app.

I don't know the actual users of this utilitiy function.  Pushing the
function into a package which they already depend on would be fine with
me:  if I were going to use zope.generations but didn't need or want
zope.app, then the root finder policy from zope.app would likely be
useless anyhow.
