Actually the change didn't happen in RTP side, but in x264 module:

x264: don't repeat headers, we should do it ourself where needed
So either that needs to be made as boolean option ot add code to RTP
output to repeat headers if requested. I think changing the encoding
code could be simpler as currently it seems to work ok if transcoding
doesn't happen (places PPS/SPS with keyframes).
Modesty is a vastly overrated virtue.
