Well, as for most of the purposes such a feature could have, do as ulillillia suggested ... simply add that script, change the skills and voíla ... only disadvantage is that you can't see it in action straight away, I give you that. So yes, for aligning models by scaling them, this is not the right solution. I think a model scaling in WED is somewhat useful, especially for fences or model walls. Since we can tile skins too, this would be pretty neat indeed.

However, for random things like your example rocks, the script Uli provided is good enough, isn't it?

Cheers
