Hmm, just looked that up, but all I found on that was one page that 
implies (sadly, with no sources referenced) it did not make it in:

However, looks like what happened instead was iframe grew a "seamless" 
attribute, which frankly looks pretty damn sweet:

Still researching browser compatibility and adoption though.

TL;DR: New in HTML5: <iframe seamless src="url" /> is the answer 
(assuming it isn't still *too* new, not sure yet)
