Yes and no.

No. The URL above is for HTTP/2 and this is a header usable in
HTTP/1.1 so is not the same. Adding this to a system that is
currently safe wrt BREACH is also perhaps not the same as doing
HTTP/2 from scratch and ending up safe wrt BREACH.

But more importantly, yes, I'm asking about the kind of analysis
that lead to the section 10.6 you point at.
