There are currently ~1500 prefixes with inconsistent origin AS.
These are trivially identifiable:

Some of them are obvious mistakes (I doubt HKSuper is supposed to
originate 4/8). But many of them are not, and the Internet works
just fine.
And as Justin said, some sizable fraction of those 1500 prefixes are
quite possibly *appearing* to Work Just Fine currently, but if
something
breaks, that will be 1500 NOC monkeys facing some difficult-to-debug
routing issues....
Considering the number of inconsistently originated prefixes has been
non-trivial for at least a decade, I have trouble believing this is a
huge threat to the internet. Or even those 1500 NOC monkeys. (And
wouldn't it be 3K - at least 2 ASNs per prefix? :)
