And is it your belief that this addresses the described attack vector?
AFAICT, it does not.

Quoting myself : 

WITH the assertion that all routers in the routing domain are RPKI enabled, and discarding RPKI INVALIDs.

 In the mixed RPKI / non-RPKI environment of today's internet, no it doesn't. This does not mean that RPKI is deficient, or the AS 0 ROA doesn't work as intended, as was stated.

AFAICT, it does not.
