No it doesn't. Its perfectly possible to do without that, wether or not
thats needed totally depends on your models implementation. For example
QStringListModel doesn't use the internalPointer/Id at all, neither should
most table-models need this. And you can even implement tree models
without, but of course they'd be somewhat slow as they'd have to traverse
the tree a lot if you don't get the parent-tree-item via the internalId or
internalPointer.
