ListView / GridItem (QQuickItemView) header and footer properties have a Component type. This is not consistent with classes from Qt Quick Controls (ApplicationWindow, Page, Dialog) and it's confusing.

There's not much sense for it to be a Component, since it is always instantiated anyway and you have a single one, unlike delegates.

Could we make it so that the footerItem property is writable to avoid having to use a Component?

typical usage: have a TextField as the header for filtering a ListView
If I want to retrieve the TextField text I have to do like so:

pattern: listView.footerItem.text

I would like this to be more explicit (and type safe? footerItem is of type Item, it's not supposed to have a text property), like so:

pattern: mySearchTextFieldId.text

That is currently not possible with a Component.

Maybe for Qt 7: make header and footer Item and not Component
