​IMHO this is too coarse simplification.

For operators if we are getting into this here vs in companion GROW doc
draft/rfc must define what sending vs receiving operator is expected to do.

​For implementation allowing any value unless policy is in place. And as
such policy must be able to validate against BGP Origin Validation database
if present and enabled on the router.

Again .. I assume we are all talking about first 4 octets only right ? Or
also second 4 octets too ?

Best,
R.
