Can you help on questions about adding VP9 support on my application with libvpx?

Hi experts,
I am to add VP9 support in my project with libvpx, can you help to answer the following questions:
1. Is there anything update for the RTP Payload Format for VP9 Video (draft-uberti-payload-vp9-01) for payload header and RTCP feedback message ?
2. For VP9, the encoded data are not packed into partitions as the way the VP8 does, i.e. there are only one partition, right ?
3. Is it correct that the application for encoder ( the sender in the case of video communication ) decide whether to send all the layers or just the base layer to the decoder( the receiver in the case of video communication ) ?
4. How the encoder get the infomation about the networking situation? by the RTCP receiver report ?
5. What API we can use to discard some layer ? and is there any exaples in the libvpx ? In this case, how to let the decoder know that some layer has been discarded ?
6. How to set the rc_end_usage? What is the case should the application use the VPX_VBR/VPX_CBR/VPX_CQ/VPX_Q ?
Your help will be really appreciated!
Best Regards,
Jim
