i do not understand your logic.
let's try to show the case
666.42.0.0/16 has a roa for as 777
666.42.1.0/24 has a roa for as 888
an announcement comes for 666.42.1.0/24 originating from as 999. are
you implying that it should be marked valid? i sure don't want it to.
an announcement for 666.42.0.0/16 from as 777 would still be valid.
so i am not sure what your point is. please clarify with a concrete
example.
