If I understand this correctly, I have a suggestion : update these files at a regular interval (15/20 min) and make them available for download with a fixed name (not containing the date).
Even better : have a route server that announces these prefixes with a :666 community so people could use it as a blackhole.
This would not remove the invalid prefixes from one's router, but at leat would prevent traffic from/to these prefixes.
In other words : a route server of prefixes that are RPKI invalid with no alternative that people could use without having an RPKI setup.
This would even work with people who have chosen do accept a default route from their upstream.
I understand this is not ideal; blacklisting a prefix that is RPKI invalid may actually help the hijacker, but blacklisting a prefix that is RPKI invalid AND that has no alternative could be useful ?
Should be considered a bogon.
