You're right, it doesn't, and the bandwidth of image hosting at that scale clearly costs someone real dollars. It's hard to imagine a good solution to the hotlinked historical images problem. Maybe a futureproof one is to maintain one's one domain with image urls that redirect to the user's current host. I think this is the best approach for book publishers. It's always frustrating to read references to blog posts etc from a book more than a few years old and then find the links are broken from a third party not maintaining the domain or changing it. Link rot is a real problem we don't talk about much.
