I don't believe there's anything currently that specifically addresses 
this for the responsive "same page changing depending on viewport 
width/zoom level" aspect. The closest the spec comes to tackling this 
concept is under its definition of "conforming alternative version" 
https://www.w3.org/TR/WCAG20/#conforming-alternate-versiondef (but, as 
discussed at length on this list earlier in the year, the different 
versions you'd see at different breakpoints aren't really "alternative 
versions" per se, as they're displayed based on factors that may be 
outside the user's control, and they're in effect the same resource, 
available under the same URI).

Having said that, I'd turn this around and say that, to my knowledge, 
WAI does not mandate the opposite of what I said either (i.e. nowhere 
does it state that all the content/features must be present in exactly 
the same place/same page). But taking the wording for conforming 
alternate version (regardless of this case not being about a strict 
"alternate") "Note 2: The alternate version does not need to be matched 
page for page with the original (e.g., the conforming alternate version 
may consist of multiple pages)." it seems that what I said above is 
reasonable, even if not explicitly mentioned.
