These days I had a chat with some co-workers saying that as the time go I fell more and more that we'll need *some kind* of size hint (it doesn't necessary need to be exactly the one that we have on QWidget/QGraphicsWidget). So I really support the idea of solving this once for all in QML itself. Making the properties read-only doesn't improve much our use case as we still would need our ImplicitSizeItem as you said. Enabling the use of a function for binding an expression to them sounds like a little bit "hackish" from my "API point of view". It should either support writing on it or not at all, otherwise it just makes the API uglier and hard to understand when looking from outside.
