So let me take my Intel hat off for a moment.

The upstream policy has always been that we don't merge things which
don't have an open usable user space. Is the HDCP encryption feature
useful on its own ? What do users get from it ?

If this is just an enabler for a lump of binary stuff in ChromeOS then I
don't think it belongs, if it is useful standalone then it seems it does
belong ?
