Lock scaling but not translation?

[bpedit]

Curious whether there's a way to lock an object, such that it doesn't scale for example, but still allow for it to be translated. 

[One of my Designer uses is for stained glass work. Once I've designed the pieces, all fitting together precisely, I need to move them around individually to fit on stencils or pattern assemblies to print out while maintaining their shapes and sizes. I often see that I've changed the proportions instead of grabbing the object to drag for translation and then have to hope I haven't missed undoing any of these errors.]

I'm not aware of a way to do this currently, the existing lock layer functionality is restrictive on locking both scaling and object transformations simultaneously without a way to toggle only just one or the other, so I think it would be a feature request.
