"rir says owen can originate route FOO"
"ROA for 157.130.1.0/24 says OWEN can originate"

Nope… ROA says (e.g.) AS1734 (or anyone willing to impersonate AS1734) can originate 192.159.10.0/24.

those seem like valuable pieces of information. Especially since I can know this through some machine parseable fashion.

I would agree if you had some way to distinguish AS1734 originating FOO from AS174 originating FOO with a prepend of AS1734.
