There is also a change to add "RFC 3448 refers to this variant of  
TFRC as TFRC-PS, for applications that might vary their packet size  
in response to congestion" in section 2.

The text in RFC 3448 referring to TFRC-PS is:

   TFRC is designed for applications that use a fixed packet size, and
   vary their sending rate in packets per second in response to
   congestion.  Some audio applications require a fixed interval of  
time
   between packets and vary their packet size instead of their packet
   rate in response to congestion.  The congestion control mechanism in
   this document cannot be used by those applications; TFRC-PS (for
   TFRC-PacketSize) is a variant of TFRC for applications that have a
   fixed sending rate but vary their packet size in response to
   congestion.  TFRC-PS will be specified in a later document.

which doesn't seem to describe the variant of TFRC described in the  
tfrc-voip draft. Was your intent with this change to equate the two?
