I'm basically fine with the wording below. The only thing I might add would be some mention of the reason why we're talking about route leaks, why they're considered a problem that should be solved in the context of SIDR, etc - mainly that there are those among the WG and operator community that believe BGPSec as currently proposed is incomplete without a method to prevent route leaks, and given the costs to deploy and manage BGPSec, the inability to protect against this problem limits its attractiveness for deployment.
This is covered in detail in the referenced drafts, but is worth including in the summary text.
