I'm not really sure what purpose that would serve, other than to make content creators feel like they are trapped creatively.  Just to clarify, by the way, "diversify" means to spread out, so I think you mean "consolidate" rather.

Personally, if I were pigeon-holed into making only one type of content, or creating for one figure, I wouldn't do this anymore.  I appreciate the concept you are getting at, but I don't think it is a good idea nor one that is likely to happen.
