Yes!
Scale should be a property of all symbols, like x,y,& z. If you don't like it don't mess with it.
I'm still flabergasted that they don't scale. So much that I'll add an idea from other hybrid CAD.
Scale 2D & 3D separately.
I use this for lighting fixture symbols. A 4" opening recessed light in 1/8" scale is too tiny. Answer is to have the 2D symbol scale with the page scale(added twist) so that when you print the one room detail at 1/2" scale the fixtures look reasonable.
There are many other items that use symbols (often with text that must scale,) that bear no relation to the 3D elements. This is the strength of VW, please use it to it's logical extent.
The overriding goal of CAD is to never draw the same thing twice. Scale is integral to the fundamental concept of drafting. Parametrics are the road to true BIM. A parameter of "scale" is nesessary.
