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. On Sun, Oct 22, 2023 at 12:57 PM William Herrin <bill@herrin.us> wrote:

He's saying that someone could come along and advertise 0.0.0.0/1 and 128.0.0.0/1 and by doing so they'd hijack every unrouted address block regardless of the block's ROA.
RPKI is unable to address this attack vector.

Section 4
A ROA with a subject of AS 0 (AS 0 ROA) is an attestation by the holder of a prefix that the prefix described in the ROA, and any more specific prefix, should not be used in a routing context.
