Hi Peter, 

That doesn't sound unreasonable, bearing in mind how much we all $ENJOY using 
the operating system precisely because the interfaces are defined and stable 
between major releases.
I would not have expected PF 4.7 and above to be backported.  

Reading between the lines of earlier posts I was getting the impression that in 
case of PF it had been decided to set the 4.5 version of PF in stone for now 
and ever more in FreeBSD. 
Could be the wrong end of the stick on my part though.

The whole problem is that the new syntax is not backward compatible
with the old syntax.  There has recently been a fairly long thread in
-hackers discussing (in part) the need for long-term stability of
interfaces.  The FreeBSD Project offers interface stability within
major versions, therefore an incompatible change in PF syntax could
not be introduced into any FreeBSD-9 or earlier branch.

It would seem a reasonable goal to port pf 4.7 (or later) into -current
so it will form part of 10.x but I can't see it appearing in 9.x.
