[css3-transforms] Problems with 3D transforms and SVG non-scaling-stroke?

Are there potential issues with SVG non-scaling-stroke and 3D Transforms? At least in WebKit I know that we first calculate the transform from screen to local transform coordinates, transform the path with this matrix and draw the path in screen coordinates to guarantee that the stroke has the same width independent of the transforms. This approach seems to be harder to realize if there are one or more 3D transforms between local coordinate space and screen coordinate space. Is there something that CSS3 Transforms [2] need to specify?
