[apologies if I am sending this multiple times, having trouble with replying]
A concept that could be borrowed from DNS side is the ability for anyone to go from the top and skip the cache(s) on an ad hoc basis. Perhaps we need a similar capability here, for anyone to query from the top. This way, a new announcement can (for example) carry a flag that says "this may look invalid but if you skip the cache you will see that it is", and suggests the receiving party to validate it from the top. Of course, two things will soon follow: some will always ask others to skip the cache, which would defeat the purpose of caching (but I would argue that it is not hard to figure out who are wasting others' bandwidth and cpu, by comparing the non-cached versions as requested and the cached versions), and this mechanism itself can be used to launch a DDoS (to which I would argue the RIRs already has enough resources to handle it, or some tricks can be perhaps applied to make this problem less significant in the first place).
