TableView selection Shift/Ctrl click behaviour absent

I've been playing with the new selection features available starting 6.5.0 and have run into some limitations. The common UI of holding Shift on the keyboard and clicking to select a range doesn't work, nor does holding Ctrl to select individual elements. I see SelectionRectangle is there to provide the equivalent mouse/finger drag UI, but it's odd that the keyboard clicking UI is absent; I think most (desktop) users would expect this functionality to be present. (Also possibly worth noting is that range based selection using the keyboard alone does appear to work, holding Shift and using the arrow keys.)

A cursory look at the code reveals that and clicks/taps are ignored completely if any modifiers are held (see QQuickTableViewPrivate::handleTap).
