Programatically: yes. I even gave some thought on how to do the dedicated 
"group-wise" handle selection, but did not come up with a good idea to make 
this obvious and not collide with object selections.

From the GUI of currently released version there is none. The latest 
development version actually can resize multiple objects at once, but only 
when they are grouped. In fact it is a transformation option built into the 
group object, used only by some output renderers.

This will most probably stay somewhat limited and still would not do what 
you are asking for.

Moving multiple handles at once is considered a useful feature by me. But 
it is not so common, that I want to jeopardize object selections by it.

Yes, almost. After looking at OOo Draw's approach, I'm uncertain if 
multiple handle selection is the way to go. Maybe Dia could follow Draw's 
example:
 - in a selection the handles of contained objects are hidden
 - there are new handles on the bounding box of the selection
 - moving these box handles apparently moves the single object
   handles proportinal to their box position

This behaviour should not be too difficulty to implement in Dia, but
there is an important lack: some object do not have resize handles.
And it's a bit unclear how they should behave.
Draw just moves text when part of the selection, but Dia has a lot more 
objects with resize restrictions. They would all just move.
