doc="" has been chosen more than an indirection because in old browsers (not supporting it), it would not lead to security issues.

     A data: URI is processed in a legacy UA even if it
     doesn't support sandboxing. What we're looking for
     is a solution where the origin can be the same as
     the parent document's, with scripting disabled, in
     UAs that support sandbox="", and where legacy UAs
     either render nothing, or, ideally, can be served a
     server-filtered alternative form of the data. I
     don't see how to do that with src="data:...".

The hidden (or ignored, ghost, etc.) attribute will remove from the DOM this part of the markup, but this part will still be reachable in all browsers not supporting the attribute. (it's more a "shrodinger" attribute.) 
That will lead to usability issue, eventually accessibility issues too. Creating the page become more complex. 

Also, search engines are suppose to do nothing with the content, authoring tools either (which I do not think is wise), there is also the case for validators. 
Should the content be ignored by the validator?
