REVISION SUMMARY
  Use the same pre-encoded normalization as bundlespecs for the stream v2 part
  requirements. As it touch the wire protocol, it needs to change before the
  release.

  I queued these first two for stable because of backwards compatibility concerns for the wire protocol. As much as it pains me to say it, the rest of the series doesn't seem appropriate for stable (even though I wish we had the functionality in 4.5).
