I agree that it's a tricky one. But in my experience, nearly 100% of all
Invalids are due to more-specifics not ROA'd vis a vis the parent aggregate.

Ultimately, it appears folk are either lazy to ROA for every prefix they
originate, or not educated enough about RPKI to do it right.

My personal preference (and best practice) would be to ROA and originate
specifically. Then again, I also say best practice is not to
de-aggregate, but alas...
