At what point would a binary have a newer internal roots hints than the 
filesystem root.hints file when a user is using #1 to keep updated? Is 
there a subset of users who would update the binary but not apt 

I guess to me, it seems better to directly address whatever failed to 
update the external root.hints than to add complexity of a "will-she 
won't-she" of using defined data files.

Also, does any of this matter? The root hints just used to find the root 
servers on initialization, and then the resolver retrieves and uses the 
current roots anyway. Resolvers need to update eventually, but it's not 
a networking-breaking level of urgency either, is it?
