Would you be expecting the industry to build something in the image of a touring car, even though it will never really be one, and with a design that will never be sent to production because that isn't the 'constructor's' business? The FIA would not stand to have a manufacturer's design being modified without the approval and involvement of that manufacturer.

And don't forget that rallying is a touring road sport. Rallycross is circuit racing.
Why are there no cross carts or sofa's in f1?

Just make a good set or rules about what is allowed and let everyone who has the means to build a car do that.
