Why would you say they have to be encoded separately?  If you cut a
stream produced with x264 just before the PPS/SPS NALs which come before
an IDR frame, each part will be a perfectly valid stream on its own.  It
may not exactly meet vbv constraints, but it will be close.  There are a
number of applications where this is valuable.
