I believe you are both right, there's no delegate recycling. I found an
old discussion about it, and why recycling might not bring many benefits
after all:

http://lists.qt-project.org/pipermail/qt-qml/2011-February/002284.html

Though indeed, it would be cool if someone would actually try
implementing recycling and then profile the results. At least in the
simplest cases, I would expect it to make a difference.
