This should either be a child of what it is attached to or use of-graph.

You had a similar discussion with Thierry last time I sent it, and it
seemed to settle on keeping that property:

Has that changed?

No, I still disagree. We already have 2 ways to describe panels: as a
child node of its controller or with of-graph. We don't need a 3rd way
even if it is simple. The problem with of-graph today is too much of
the parsing is left to the individual drivers. We need to fix that and
make it be handled by common code.

Ok. I'm guessing from your answer you prefer of-graph over a child
node ?
