I'm afraid I could not get the question:
Do you mean you want to have an assembly reference in the web.config (e.g. using a GAC-reference)? If this is what you asked, you already have it: having the Telerik.Web.UI assembly in the GAC would list a GAC entry in the Telerik.Web.UI assembly selector dropdown. Once selected, the web.config would be updated accordingly.
On the other hand, if you meant BindingRedirects as a need, this is indeed a good suggestion which we will try implementing in a release as soon as possible.
