Should tMR allow .blend files?

[Sir Teatei Moonlight]

I posted this idea a bit ago in the general suggestions thread, but it only garnered minimal discussion, so I'm bringing it to its own topic for greater visibility.

The current rules for model submission formats are that:

• There must be either a .dae or .obj.
  
• There may be a .fbx or .smd, if the above is still true.
  
• There must not be anything else (such as .blend) because they are proprietary. Exception: For edited/custom models, something else can be allowed.
  

I am putting forth two premises:

• The current standards are outdated. .dae does not support normals. .obj doesn't support rigging or vertex colours and requires an additional .mtl file. Neither handles more than one UV map very well, if at all. .fbx is opaque (unlike the other three) and so cannot have minor issues fixed by mods. .smd has been considered outdated by its main audience for several years. As a submitter, I am finding it increasingly difficult to work around these problems with modern game models (it's part of why I haven't beeen submitting much recently).
  
• .blend, while proprietary, is free and open source. There is a high likelihood that users downloading models from tMR are already planning to bring them into Blender. Giving them a .blend to begin with will decrease initial friction by a lot.
  

Given the above, I would like to suggest that .blend be made a generally legal secondary format. It can't be a primary format because it still is proprietary (I presume), but it would allow the proper retaining of so many more model properties than the current formats, and is likely to have a large "market share" of users who can just open it up and not need to make their own materials.
