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.
