Scrollbars on *View or better VirtualFlow based UI elements

The constant hiding of the horizontal (ListView & TreeView) and vertical
(TreeView) makes the interaction with the control very noisy because the
viewport size always changes e.g. when expanding & collapsing and or
e.g. scrolling a list with cells of different sizes.

The native UI-Toolkits (at least OS-X and IIRC) don't do this and always
reserve a scrollbar area which makes interacting with the control IMHO a
lot better.

I looked into VirtualFlow to see if I could hack myself (via reflection)
into it and make the scrollbars show up all time but unless I've looked
at the wrong places I could not find anything I could do. Am I right?
What do others think?
