So, if there's more than 4 billion ants... what are they going to do?

there will never be more than 4 billion ants.

 I wonder when (or if ever) we'll have such a discussion

Well, filtering in the data plane is slightly easier because 
a single subnet can cover all traffic coming from individual 
sources or going to individual destinations.

In the control plane, the industry like to filter on 
specific prefixes agreed between customer and provider, 
especially when using automated tools such as RPSL. This can 
get hairy as configurations become large, where a single 
entry with le 24 or le 48 could have sufficed.

On the other hand, if you're not automating control plane 
filters to some extent, it becomes messy as you get bigger.

 With ROAs published and a small percentage (order of 5%)
 of the largest ISPs doing route origin validation, this
 would filter the incorrect announcement and result in
 about ~98% globally correct routes in the 35000 ASes
 (this work is done a couple years ago).  With no route
 origin validation (or any other filtering) the
 percentage of correct routes at the ASes would be ~25%
 globally.  Again, this was a specific scenario.

So do you know whether anyone has any idea about what the 
top 10 global carriers are doing re: RPKI?

Thinking? Justifying? Testing? Ignoring?

 Right, we didn't include that in our analysis because we
 didn't have a good sense for how many ISPs actually do
 filter their downstream downstreams. So we chose to give
 a conservative estimate of the impact of prefix
 filtering in partial deployment: we assumed that no one
 filters their downstreams downstreams.  I'm honestly not
 sure exactly what including this assumption would do to
 our results, except to say that it would make them
 better (ie. that more attacks would be stopped).  Might
 be a good experiment for one of my summer interns.

I've typically been on the side where we filter just the 
downstream and apply AS_PATH filtering liberally for their 
downstreams.

At $current_job, we're now filtering both downstream and 
downstream's downstreams on AS_PATH + prefix list, taking 
the prefix aggregate and suffixing le 24 or le 48.

We are now thinking about how to scale this without using 
RPSL, as that creates lots and lots of clutter in the 
configuration, as well as sub-optimal forwarding when 
customers are sending routes you aren't accepting when they 
forget that RPSL-based filtering is prefix-specific.

Large Scale aNt will be good enough. Plus this has security advantages.

This has been a solved problem for a long time.  You just need to 
implement Virtual Local Ant Nest (VLAN) and use overlapping local 
address schemes.
