Indeed, I believe you've now captured the essence of why manifests
exists at all. This is what rpki-client & FORT seem to have implemented.

Other than the hashes matching & files being present, additional
conditions apply: the manifest & EE certificate need to be valid,
current, latest, correctly encoded, part of the cert chain, CRL present,
etc.

Kind regards,
