Best Practices for QML and Qt Quick should encourage declarative bindings over imperative assignments

https://doc.qt.io/qt-5/qtquick-bestpractices.html

This is an unspoken rule that should be spoken.

• Imperative code interferes with tooling, as it requires JavaScript, which e.g. Qt Quick Designer doesn't support.
• It delays errors that could be found at build time (with qtquickcompiler?) to run time.
• It's slow. All your bindings are first evaluated with null objects and then again with the real objects.
