In my opinion as the developer of the SeattleIX/SIX's strict route server 
filtering technology...

RPKI is secure and thus preferred over OriginAS whois. The OriginAS data 
we use is synthesized from the whois data by a third party and thus is 
subject to tampering. Even if we queried directly from ARIN, there is a 
risk of man-in-the-middle attacks.

At the SIX, we prioritize RPKI information over IRR and ARIN OriginAS 
data. Details of this are at: https://www.seattleix.net/rs-drops

The retirement of OriginAS as a trusted source of data should happen since 
RPKI is a superior cryptographically secure replacement. That said, for 
legacy space not covered by an LRSA, it would be good to have a 
cryptographically secure source of truth via the ARIN RPKI hierarchy.

Thanks,
Chris
