Attacker has no incentive to honor existing AS path, attacker can rewrite it as they wish. Anyhow I think some people think about RPKI in a way too binary manner 'because it is not secure, it is not useful'. Yes, AS_PATH authenticity is an open problem, but this doesn't mean RPKI is useless. Most of our BGP outages are not malicious, RPKI helps a lot there and RPKI creates a higher quality database for prefix origin information than what we have had. -- ++ytti
