On the face of it, yes.  Especially because different redirect response 
codes have different semantics (well, in theory), so some headers may 
need to be preserved across some of them but not others.  And without 
knowing the meaning of the header, it's impossible to say when it should 
be preserved across the redirect and when it only makes sense in the 
context of the original request.
