I have implemented it :
http://josm.openstreetmap.de/ticket/5652

Could someone consider it for integration ?

This is not done yet, one major reason is that we have first to separate the selection mode from the rotation/scaling mode.

Right now, rotation is done with CTRL SHIFT and scaling with CTRL ALT. Not very user friendly, and pretty limiting other features that we miss  but that make sense :
- modifier for discrete steps transformation (rotating by multipliers of 45°, scaling +/- multipliers of 100%)
- modifier for X / Y scaling only

I will try to find some time to experiment and see how other tools are behaving.
