But most apps do so, I think. I moved the getRootFolder function to zope.app.generations from zope.app.zopeappgenerations some months ago as it was the only reason I needed the zope.app.zopeappgenerations package.

What about a condition? Only when zope.app.publication is available, the function gets defined. So we could get rid of it as a dependency and do not need a separate package for this function.

No it does not use it itself.
