Microsoft's concern that a technology be able to pass their security review process is reasonable, and similar matters were the subject of a large proportion of the discussions leading to WebGL's standardization I also suspect that whatever hardening they applied to the low-level D3D API wrapped by Silverlight 3D can be applied to a Microsoft WebGL implementation as well.

Underneath the covers, Windows uses the Direct3D interface for accelerated 3D graphics, but Mac OS X uses OpenGL. In a response, Mike Shaver, Mozilla's vice president of technical strategy, observed that the new Silverlight 5 plug-in from Microsoft manages to pull off the feat, even with a cross-platform design that extends to Mac OS X.
"In its current form, WebGL is not a technology Microsoft can endorse from a security perspective." "We believe that WebGL will likely become an ongoing source of hard-to-fix vulnerabilities," Microsoft said. Microsoft, though, is worried that it's too insecure because it exposes new low-level interfaces to downloaded code, especially given that responsibilities for closing security holes lies in part with graphics hardware makers who lack experience in the area. WebGL opens up online possibilities such as virtual worlds and graphically rich games, and it's built into Mozilla's Firefox and Google's Chrome today. WebGL, a new standard from Khronos Group, lets Web programmers add hardware-accelerated 3D graphics to the Web with an interface that mirrors the OpenGL ES 2.0 standard used among other places in Android and iOS devices.
Mozilla has answered Microsoft's concern that WebGL raises too many security risks with the observation that Microsoft itself has accepted the same risks with 3D interface technology coming with its own Silverlight browser plug-in.
