Sitefinity uses KendoAll everywhere, here's an example of how it's used CMS-wide
https://github.com/Sitefinity/feather/blob/a9a417115096af67629603cf0eaf52e8a6810d06/Telerik.Sitefinity.Frontend/Mvc/Views/Designer/Designer.cshtml#L53

The basic idea is that when the page is built at runtime all the references to the script get combined and it's only served once.  So the stock widgets just all reference KendoAll and if there's 100 widgets on a page that the user creates, KendoAll only comes down once...

So in the SF backend we can set what "ScriptRef.KendoAll" means... like which script it points to, or even to use the CDN version.

Typically what I do to cut the size is to change the KendoAll script to KendoWeb CDN because nothing in Sitefinity uses KendoMobile so why constantly deliver the massive bundle.

However there's been a bunch of times where KendoDataViz has been required on the sites, and now I'm stuck... because you can't just add KendoWeb and KendoDataviz seperatly on a page due to the overlap of functionality.

Option 1: Change the entire site back to KendoAll
Option 2: Generate a custom build and use that

Problem with option 1 is I'm back to delivering a couple meg file to users

Problem with option 2 is I can no longer use a CDN, and every release I'm having to keep re-generating a new bundle file.

It would be very very very nice if a pre-generated DataViz+Web (and seperate DataViz+Mobile) build was available on the CDN to use.
