So - the situation is understood, but the question arises, what does this have in common with a global hypertext system for communication.

Maybe all this functionality should be removed into a kind of plugin, similarly to how it was done with Flash and Java applets and other ancient history. Maybe sandboxed, yes.

Maybe the parts of that kind of plugin relating to DOM, to execution, to interfaces should be standardized.

Maybe such a page should look more like a LabView control model or like a Hypercard application, than what there is now.

One huge benefit would be that Google goes out of business.
